No, I didn't.  Adding a call to setlocale to locale-info, even if we
want to add an argument for the caller to control the locale, is
trivial.

Which property will help here? we don't have such properties.  they
need to be designed and implemented.

How would you implement locale-downcase?  Are you familiar with how
Emacs case tables work?

And even if we had locale-downcase, which locale would you pass to it
in any given use case?

Please note that I'm not saying these issues cannot be solved -- they
can.  I'm saying that designing them requires non-trivial thought,
something we didn't yet do.
