These are fine from my POV. They aren't shell scripts, so they are

This should be taken off the page. This is explicitly not the place to
set arbitrary environment variables.

That would be a bug in accounts-service & friends though. The PAM ones
have a rather simple line format, so it isn't hard to change existing
ones, and the code goes through some effort to not overwrite user
settings and keep the format nice.

As Oliver said, /etc/profile.d/ is better. /etc/profile is maintained
by packages (although not as conffile) and it's already quite complex,
so it's easy for users to break it.

Many thanks! Keeping docs up to date is indeed very important and
