I’d prefer to stay with the AFF syntax which is well established.
I wonder if the latest, virtually frozen FontForge supports the
current AFF syntax or still uses an earlier version. Before AFF was
complete George added the missing functionality but Adobe did not
accept his additions. The former luatex support was probably based
on George's modifications to the AFF syntax.
Hans and Taco know better, but I suppose a newer implementation of
AFF in mkiv could be done in lua without touching the binary.
Right, the version of FontForge included in LuaTeX uses the old syntax,
FontForge has dropped it for the new Adobe syntax for few years now, but
it didn’t make its way into LuaTeX.

But anyway, this may very well be beyond Hans' current plans for
font trickery, but it's fun to discuss possibilities.
I think there is already some (not documented way) to achieve the same
effect in pure Lua code (Hans uses it to implement tlig and the likes).
indeed. however the biggest challenge in patching a font runtime is
where to inject the patches in the look up sequence ...
