Announcement text:

The section of the Python packaging appendix relating to manual byte compilation has been amended with a new section applying to Fedora 29 and newer only. Because this is a rarely-trafficked section of the guidelines and the change mandates modifications to a number of packages, I will summarize here:

If your package installs files with names ending in ".py" outside of the standard directories for python files (/usr/lib(64)?/python\d.\d) then in rawhide you must disable automatic byte compilation of files outside of these directories by adding "%global _python_bytecompile_extra 0" to your spec and then, if necessary, manually byte-compile those files with a specific python version using the %py_byte_compile macro.

There are on the order of 500 packages which will need attention to fix this before the default value of %_python_bytecompile_extra becomes 0 (and potentially breaks many of those packages) in a future release. Lists of these packages will be posted separately on the devel list.
