For Python, it's already reported at: https://issues.guix.gnu.org/60733.
And even implemented here: https://issues.guix.gnu.org/60849.

Why it hasn't been merged yet is because it's coupled with a more daring
change (unified build system for Python) and there were comments that
this should be an all or nothing change, so I'd need to workout all the
build systems and see what breakage happens at the global scale, which
is a rather large undertaking.

Maybe it could be decoupled from that change and tested in isolation,
pushed first; we'd loose the benefit of the later change which is the
ability to avoid wrapping native-inputs in our wrappers.
