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.
