I think it was more of an impasse.

.pyo's can also break python programs.  The "optimizations" include
things like removing docstrings which programs may depend upon to

Is %{find_lang} more trouble than it's worth?  It similarly is just a
space savings.

1) Current Extras packages already adhere to this standard.

2) We must include the pyo's in the %files section either as %ghost or
as normal files otherwise they won't get removed from the system once
they are created.

3) It's not that hard to implement this in a spec file.  It's also not
that hard to implement a script to do it for you.

Attached is a script that takes a directory and generates a file list.
It can replace a common %files idiom such as:
  %{find_pyfiles} %{python_sitelib}/docutils docutils

  %files -f docutils.pyfiles

There are other solutions as well (something more like 
%find_lang, for instance, that scans the whole %buildroot for python
files and correctly lists those files and the directories they reside in
for instance.)


PS Second attachment is a patch which adds the find_pyfiles macro to
rpm/redhat/macros and adds this file to the rpm/redhat/macros/
