Please don't copy the PYTHON_* insanity here.  The only reason for
PYTHON_SINGLE_TARGET, as I keep repeating, is that we *needed* a sane
default of py2+py3 for a lot of packages, without causing REQUIRED_USE
violations all over the place.

I don't think Lua situation is similar.  That is, I don't think you can
pinpoint a combination of 2 or more default 'targets' and a single
'target' that would work for the majority of packages.  Just use
a single USE_EXPAND combined with REQUIRED_USE and sane defaults.
