Indeed.  I think that setting PROMPT_COMMAND as an array in
the default configuration would be the place to start.  Then
packages which enable such functionality can be added with
more granularity.

If the desktop working group wants to default to having such
a configuration enabled, it can be done without affecting
the server images, etc.  And folks can easily opt-out even
on the desktop.  (I'd still prefer if it was opt-in for the
desktop, but that's just an opinion.)

That makes it easier to add snippets to /etc/profile.d
rather than coordinating everything via the setup package.
Hard-coding a default for everyone which leaves a good
number of folks unhappy in either case is not ideal.
