I looked into the latest Harfbuzz internals, and it looks like the list
of supported OpenType features is manually maintained. Not all the
features listed on the Microsoft feature registry are supported, but
many are. The full list can be found here:

https://github.com/behdad/harfbuzz/blob/9813be3d1212eef5a525d64978e0bb2032cd44d9/src/hb-coretext.cc#L439

This list covers pretty much all likely candidates a user is going to
encounter or want to use in modern fonts, so it probably isn't worth
listing each of the supported features.
