Doing the code inspection of existing preexec_fn= users within our codebase at work is revealing.  But those seem to be the bulk of uses.

I expect this deprecation to take a while.  Ex: if we mark it as PendingDeprecationWarning in 3.10, I'd still wait until _at least_ 3.13 to remove it.

Code using it often has a long legacy and may be written to run on a wide variety of Python versions.  It's painful to do so when features you need in order to stop using it are still only in modern versions.
