However, this approach would break with Python 3.5 (where pyo data is merged
into *.pyc data)
To be more precise, AFAIU there's no "merging", *.pyo goes away but in
exchange there are actually two new optimized bytecode files,
*.opt-1.pyc and *.opt-2.pyc:
https://www.python.org/dev/peps/pep-0488/
If you want to exclude them from packages, they should be there listed
as %ghost so they're removed in case they get generated by something
run with -O or -OO. Ditto *.pyo if you intend to exclude them from
python < 3.5 packages.
Also, be careful with measuring space savings when working with *.pyo.
It is a common case that *.pyc and *.pyo are identical, and when they
are rpmbuild already hardlinks them.
