I agree. We have this enabled in our distribution, which is used by a
couple of thousand people (among them people working with various
Asian fonts), and I haven't received any complaints.
Thanks for the excellent work.
Another problem, obviously across ports, remains. When many faces
have been defined during the current session, creating new frames
slows down to a full second or so. The problem can be recreated with
packages such as color-theme, where you can flick through a lot of
themes, which AFAIK irreversibly defines a number of faces. Having
several hundred of them is not untypical.
A while ago I traced this down to the fact that all faces get copied
when a frame is created.
I reported the issue here and you made some improvements to the
Carbon port, but the general problems remains.
