I really hate dissecting posts, but there's so much willful ignorance in the latest response from Little Rooster that I have little choice.

Because the developers create these ROMs specifically to hone their skills or simply because they want to. They create these ROMs for their own private use and generously share what they have made with the rest of us. A serious ROM developer would not use Xposed in their work. They do not embed root into their ROM packages because it isn't recommended by the developer of Magisk for one, and for another embedding root into system would compromise system integrity, meaning apps that detect root will not run.

Serious app developers DO care if your phone is rooted or not. Pokemon Go will not run on a rooted system unless root is hidden, and even then there isn't a 100% guarantee that the app will work. Usually it's because Nintendo has found a way to detect Magisk. There are other apps where this occurs, but Pokemon Go is the best known.

Not disagreeing with you here, as the call center employees do run from a script. However, the call centers are geared towards the average consumer, and XDA members - for the most part - are not the average consumer. Keep in mind that the 8 million members here is a minuscule fraction of 1% of the planet's population. It would be senseless for a company, whether a phone manufacturer or app developer, to gear their hotlines to us.

On a Touchwiz device from 2014, they piled too much into the ROM and everything was on, which did affect RAM, performance, and battery drain. Root allows you to fix a lot of the problems, but the only effective method of fixing the problem is by getting rid of Touchwiz.

Calling an unrooted system "Kids Mode" is an insult to every Linux user on the planet. Basic principles for Linux tell the user to NEVER run as root. When we run our smartphones and tablets we do so in root mode, because we don't have a sudo command in Android. This is by design, as Android was never intended to have a root mode visible to the user. In fact Google actively hid it.

My devices do not run Xposed, and they never will. My I9505 uses an AOSP-based ROM because I don't like Touchwiz. I guarantee that it would run circles around your device, simply because it doesn't have the overhead of Touchwiz OR Xposed. Of course neither of them can compete with my Pixel 2 XL running rooted stock, but I digress.

Already asked and answered.

They're smart for not doing so. Trying to troubleshoot problems with an Xposed-infested system is an exercise in futility. But, since you seem hell bound and determined to promote Xposed, why don't you talk to the developers and actually ask them why they don't use Xposed. You're asking me, and I know why I wouldn't use Xposed: it gives me too much of a headache to deal with. The developers however are the only ones who could actually answer you.

At this point, I think this line of discussion has been exhausted, and nothing else productive can be gleaned from it. Clearly you are an Xposed fan, but if you are unable to see just why developers do not use Xposed in their ROMs, then you are both blind and foolish.
