Ah, so this only removes some deprecated variables?  Yes, we tend to
leave them for a very long time, up to five major releases.  They are
then generally removed en masse; in Emacs 28 we are removing most things
deprecated in Emacs 23.

In Emacs 29, I expect that we will remove most things deprecated in
Emacs 24.

You can just add "-close" to the email address of the bug number to
close it, as in "50006-done@debbugs.gnu.org".

I did that now, mostly so that we don't forget about it.
