"Constant" is the definition of a fixed uid. If there is need for a
fixed uid, ask for one (yes, there _seems_ to be currently no space, but
that is another issue), if not use useradd -r.

sure - oops, the admin forgot to configure fedora-usermgmt on machine
number 23. Now all uid/gid are messed up.

That's an extremly fragile design, and if it even involves using these
uid/gid in a security context a very fragile security setup.

From any POV I look at it, this design is flawed ...

As Enrico pointed out: You need to adjust or violate the LSB.

But we're fixing an issue which is none. I'm rather convinced that all
packages using fedora-usermgmt don't need fixed uids. Or at least
present a counter-example, where a package needs it. And then please
explain how it can need a fixed uid/gid and still have survived that
long in the fedora-usermgmt-defaults-to-useradd-r setup.

We're really just vapour-talking. fedora-usermgmt "fixes" something
that wasn't broken to begin with, and the fix is more broken than
anything we try to suggest fedora-usermgmt would be able to fix.
