Er, you seem to be forgetting that a disjunction of fixed strings *is*
a regex. Ie, your API "can't work" either.
It can avoid the ‘entirely inappropriate pattern for the given charset’
aspect, and that is important. Remember that the existing API says nothing
about _where_ the charset-registry pattern matches; "courier" is an
appropriate value for it.
But it does, so I still think:

Agreed, I don’t propose backporting anything to 21.4. But my understanding
is that the cache works; the performance problems are a result of the design
being heinous, not any implementation bug. What makes you think the cache
doesn’t work, if that is your understanding?
