Probably not, but I've never actually seen the stable ABI used in
practice (and I don't know if cffi restricts itself to the stable
ABI). I'm not sure that any toolchain (such as bdist_wininst or wheel)
really supports it (in the sense that they tend to make the assumption
that if there is a C extension, the code is version-specific).

None of these are insurmountable problems, though.
