IMO, yes. I didn't change the quoting in the docs, since https://github.com/pandas-dev/pandas/issues/19750 hasn't been resolved (just replied there).

Comments:
I didn't really know where to put this in the whatsnew file. Because as a revert it does not really fit in "bug fixes" IMO. 
Any ideas? (I now added it in a section "regressions")
Regressions seems fine, unless you read it as "We've introduced these new regressions!" :)
I can make the title "Fixed regressions" :-)

I think I addressed your review's comments
> minor comment. can you elaborate on why you think the return values are the right thing here? e.g. is this from the PyTables api directly? e.g. what is the point of having the groups and subkeys? wouldn't you just care about the subkeys?

It was made this way in the original PR, I didn't see any reason to change it. It's a refinement from the PyTables api, I guess the original author  @stephenpascoe  found it convenient. 

I made the docs change in the last forced push.
merged via https://github.com/pandas-dev/pandas/commit/45e55af9cf74aede00a8b10f8922537f285a573a

for some reason couldn't push to your remote, so manually merged.

thanks!
DOC: fix mistake in Series.str.cat
State: closed

Fix error in API-docstring that was introduced at the end of #20347 due to timepressure for the v.0.23-cutoff: removed functionality that categorical callers get categorical output, but forgot to adapt doc-string.

Unfortunately, this survived both #20347 and the follow-up, but since v.0.23.1 is coming soon, I didn't wanna let this opportunity pass.

Should this be in the 0.24.0 whatsnew instead?  The xref'd PR has a 0.24.0 milestone.  Not opposed to this going in 0.23.1, just want to make sure this is aligned with the xref'd PR.
Good question. Since it's a bug fix I am assuming v0.23.1 but can move if we want
