I'd doubt that. It's well known that glibc 2.28 (what RHEL8 upgraded
to) included changes that affected everybody by changing the sort
order of common symbols like '-' (though every upgrade potentially
contains subtle changes affecting just a few specific languages), but
I consider the recent big change an improvement because it now agrees
more often with other operating systems and libraries that use CLDR.
Even if you are right that FFFF's sort-high rule should be exposed to
users (need references), RHEL7 was also wrong in that case.

I don't know, but since you know perl, it might be easy to make a
demonstration with https://metacpan.org/pod/Unicode::ICU::Collator.
Looks as simple as $collator->sort(my_list).
