Not everything has been updated to use %{__python2} or %{__python3}, and of those that haven't been updated, many probably are not ready for switching to python3. I think it would be better to avoid a flag day, and simply slowly switch packages one by one. > * All applications that use only a single python version MUST use > python3 (unless they have a good reason not to do so). Do you intend to file bugs for all such packages or notify maintainers in some other way?
