I also concur; it is entirely reasonable to have a mechanism that code
can use when it knows exactly what locale to use. Point (c) — the
refactoring once such an API exists — seems plain sensible; no point in
writing the code twice.

Here's some back-up reasoning. :-) We also need to figure out what to do
about locales and TclOO (and itcl, and so on) as the existing mechanism
— binding current locale to namespace — is unworkable (each object has
its own namespace, with no inheritance between them). Having a mechanism
that takes an explicit locale makes fixing things much simpler as it
means that the msgcat package doesn't need to understand TclOO's
inheritance mechanism itself; it can delegate to some class that holds
that piece of the smarts.
