No, not really.  AUCTeX does it at least since 2004 where
`LaTeX-syntactic-comments' was named
`LaTeX-format-comment-syntax-aware'.  And `electric-indent-mode' is on
by default since 2013, too (I don't know what was the first emacs
version with that change).  So indeed, it also baffles me that nobody
spotted the annoying newline behavior until now.

Well, maybe, maybe not.  I see as `LaTeX-syntactic-comments' as
"consider the contents of comments to be LaTeX entities, too", and then
it makes sense for TAB to end up at the actual content of the comment
and not the comment starter.

I can follow your reasoning but given that you are not really opposed to
the current behavior and neither are other users, let's just keep it
as-is.
