Seems like the sensible way is to have the person wanting to do the work sign up as co-maintainer, and take charge of the Rawhide branch of the package. Care must then be taken to make sure the F-12 and rawhide packages don't diverge much, apart from any Python 3 fixes required. Any fix that is 2.x-compatible should probably be merged to the F-12 build as well, and upstreamed. > The more difficult case is when the python module is emitted as part of > the build of a larger module.
