The obvious approach is to do both (in exactly the manner of
{-fffi, -farrows, -fwith}), namely to introduce a separate flag
for each extension, but (temporarily) retain -fglasgow-exts as
a catch-all for the complete set. Eventually, -fglasgow-exts
could disappear.
With this suggestion, I would certainly be in favour of separate
flags for existing extensions.
