I don't think the hammer is really that big; it seems like a relatively
small extension to me. The code for checking ABI patterns is already
there, this just wires it up to a couple of additional functions.

I actually think it would make more sense to call python_mod_optimize
using python_execute_function, but I think that would require a
backward-incompatible API change.

That would take care of this specific package, yes. However, I still
think it would be nice to have a workaround available.
