[Fedora-packaging] Should python(abi) provides/requires query %{_prefix} or hardcoded value?

[Miro Hrončok]

Hello,

in Python, we provide python(abi) = X.Y for packages owning /usr/bin/pythonX.Y.

We also require python(abi) = X.Y for packages owning files in 
/usr/lib(64)?/pythonX.Y/.

My question is: When %_prefix is redefined (eg in flatpaks), should those 
automatic provides/requires stay or go away?

Technically speaking, should we grep for /usr (hardcoded) or for %_prefix?

Thanks,
