It won't work in those cases. Do you have explicit examples? I suspect this won't come up much as Rust has, IME, much broader target support. (Including platforms without a GPOS)
I can't come up with any cases where cpython would compile that rustc can't target. There are some more niche interpreters that can run on embedded stuff with no rustc support, but they are also subsets of python so it isn't like you can just pull a wheel file and expect it to work
