You should be able to use the %pycached macro and if that breaks flatpaks, we
should amend that macro to support that instead of adding `%if ! 0%{?flatpak}`
to individual spec files. The idea behind this macro is to be able to do changes
in one place.
However, it would help to know the reason why flatpaks don't have bytecode
caches. This is the first time I've seen this mentioned. It will require other
code to be adapted as well, for example %pyproject_save_files.
I believe this is because flatpaks are installed into /app, but the python bytecode compiler only does it for /usr.
brp-python-bytecompile has:
... which should use prefix instead of hardcoding /usr (or alternatively scan both /usr and /app).
