Titlecasing for Georgian was not completely thought through before
Mtavruli was added. As I noted in my earlier comment on this thread, the
titlecase mapping values for Mkhredruli were added late in the process,
when it became clear that not doing so would result in inappropriate
outcomes for existing Mkhredruli text.

I don't think there is a fully-worked out position on this, but adding a
Simple_Titlecase mapping for Mtavruli to Mkhedruli would, I suspect,
just further muddy waters for implementers, because it would be in
effect saying that an uppercase letter titlecases by shifting to its
lowercase mapping. A headscratcher, at the very least.

Note that with the current mappings as they are, Changes_When_Titlecased
is False for all Mkhedruli and for all Mtavruli characters, which I
think is the desired state of affairs. A titlecasing string operation of
Mtavruli that does something other than just leave the string alone
should, IMO, be documented as doing something extra and *should* have to
do additional processing.
