>The other side of the issue is extroverts wanting to extrovert,

I *really* wish people would stop with this overly simplified take. I'm an introvert. WFH was something before the pandemic I thought I wanted. It was miserable. Turns out that when you're an introvert, you don't have great "maintaining a social relationship" skills and things that happen naturally when you're forced by proximity to work and interact with other people now require dedicating specific effort towards. If trying to maintain a good social relationship with my co-workers was a drain on my energy levels before, having to do the things necessary to do that AND also having to put extra effort into making it happen was even more draining.

And that doesn't even get into the other more subtle "anti-introvert" consequences of WFH. Like requiring extensive use of chat systems, leading to extreme self-consciousness over the fact that every "hey I'm sure I'm being stupid here, can you help me find the obvious thing I'm missing" or "I swear I've seen this documented before but confluence is awful, can someone point me at the instructions for Foo" moment is now a part of the permanent company record. And more than that, it's no longer a simple call over the cube wall to my immediate co-workers, it's in a public channel broadcast to everyone who happens to be there.

Or the number of times we'd be discussing something and then have to deal with a micro-manager butting in the next day after they'd read half the thread and mis-interpreted everything was massively increased. And yes, in theory you can have a separate channel for every combination of people you might want to be talking to at any given time, but in practice you often need to share things or bring in outside people from time to time and having to copy context to an entirely new channel every single time is a waste of time and energy and simply broken compared to being able to just include people in the channel.

Or the fact that because all communication now has to happen via text medium, if you want to keep an eye on something, you literally have to stop and context switch to keep that eye on it. It's no longer possible to work on one thing and listen with half an ear to your teammates on something else unless everyone wants to be on headsets and in an open mic call all day long.

Or the incessant pings of notifications all day long. Yes you can mute notifications, but you very quickly find out that if you're not at least then dedicating specific times in the middle of your day to again stop and context switch, you'll be missing things you probably didn't want to miss, or be failing to respond to requests and questions. It's like all the worst parts of coming back from vacation to a fully loaded inbox, but every day. Made even worse because people know you're not on vacation so now you have to balance reducing your context switching against not delaying responses too long so you don't start looking like an ass or a flake. And sure, your co-workers are probably in the same boat and get it just fine, but again remember that all of this is public and timestamped and someone just might decide to take an interest in how long it takes you to respond.

Or the fact that now every meeting is probably recorded, and you need to be eternally vigilant about an open mic and camera.

Or the lack of physical and mental separation of your work space and your home. Not everyone is blessed enough to live in a house where they can dedicate one whole room to an office space. A number of my "unwind after work" hobbies were on permanent hiatus because the space they would have occupied was instead my office space. Turns out when you're not getting any of the already limited social interaction you normally get as an introvert and mix in not being able to engage in your preferred hobbies, things get miserable really quickly.

To be clear, I prefer a flexible policy. There are absolutely benefits to being able to work from home when needed or wanted. But I came out of the pandemic STRONGLY preferring to be in the office as often as I could. And yes I know things will be different for different people; some folks won't be bothered by the things that bothered me. But that's also my point. We're all different, and just because I'm an introvert doesn't mean I'm a misanthropic hermit either.
