    That, and the ensuing endless arguments about what should the default
    colors be.

Well, then, as I say, either 1) wait until after the release, to give people
lots of time to argue about the best defaults ;-), or 2) define new faces
with possibly imperfect defaults, and let users provide feedback that will
help determine better defaults.

IMO, there will be more argument and frustration if this is implemented
using existing faces: 1) the defaults are just as likely to be bad, 2) the
same discussion will have been skipped (not necessarily a bad thing, IMO),
and 3) there will be no way for users to experiment with different values in
different contexts (e.g. diff backgrounds) and provide feedback to improve
the default values.

If existing faces are reused, however, then users can't customize this
feature without also inadvertently customizing some other features, and
probably what works well for one context will not work well for another.
Faces are essentially global variables; they should be as specific as are
user variables.
