      A: It doesn't benefit the community to reference a Unicode version that is outdated by the time the standard is published.
It doesn't help anyone to have a standard, a specification, that changes its meaning next week. There are controlled mechanisms
for choosing when to update to a newer specification, and all those lose their effective meaning if the meaning of the specification
changes from underneath everyone's feet.

This is why we shouldn't backport features, and why we shouldn't have the portable featureset change within a standard, including
the things we're based on, things we reference, whether normatively or otherwise, when their updates change how the language
works.

GCC 10 isn't going to get updates reflecting an updated Unicode standard. Neither is GCC 17 in the future, when the time comes that
it's a no-longer-supported version.
