It'd only be an issue if they want to compile from source, right?
We're not speaking of changing the runtime prerequisites, IIUC.

I think it's really important that we continue to run on all of the
supported Linux distributions and even some recently-out-of-support
ones if they are popular. My experience is that many people stay on
whatever version of RHEL they've got for quite a long time. I think
we'll be doing ourselves a disservice if such people find that they
can't easily upgrade to newer versions of PostgreSQL without
installing a bunch of new software and/or upgrading software they've
already got on the machine.

On the other hand, the class of users that I'm thinking about does not
typically install anything from source, so they are not directly
impacted by build prerequisites.
