How would you feel if there was a better way to "lock down" the
behavior using an extension?

I have a patchset here:

https://www.postgresql.org/message-id/78a1b434ff40510dc5aaabe986299a09f4da90cf.camel%40j-davis.com

that changes the implementation of collation and ctype to use method
tables rather than branching, and it also introduces some hooks that
can be used to replace the method tables with whatever you want.
