AFAIK the current version of microtype already supports microtype?
Or is it only for non-OpenType fonts?

If microtype is already working for LuaTeX I'd prefer to keep separate packages, but if it makes things convenient then provide an interface to microtype through fontspec itself.

But I agree eventually microtype and fontspec belong together.
