Comment (by mpickering):

 This is very vague. You say that the semantics are different but how have
 you observed this? `INLINABLE` doesn't do anything about "forcing
 specialisation" so I'm unclear what you mean. If I was to guess I would
 say that `-fexpose-all-unfoldings` exposes optimised unfoldings rather
 than unoptimised unfoldings like `INLINABLE`.

 Now to make progress, do you have a small code sample which behaves
 differently with `INLINABLE` vs `-fexpose-all-unfoldings`?
