Yes, but the range under 500 is already defined as "special". I don't
it's unreasonable for a certain subset of that to be now marked as reserved
for Fedora Extras packages. We could make it start at 300 to be less likely
to conflict with random "useradd -r" done earlier.
Assigning fixed IDs in this range would violate LSB which states

That's why it would be a bad idea when Fedora Extras claims fixed UIDs
there. I agree with you that every large organisation has its assigned
UID ranges and it will not be possible to find a free range which can be
assigned to Fedora Extras.
Perhaps we could find such a range in the 32bit UID space which is allowed
by Linux; but I am not sure whether we cause portability problems.
