here is a package that contains a build system that, unlike the python3-numpy team, relies exclusively on python3-all. like python3-gmpy2, note that it does not contain enumeration of the minor versions of python. its control file does not list multiple versions of python3, either, choosing instead to rely on the macros.
thus this particular package is critically subject to your arbitrary and unthinking "whims", where python3-numpy is not. i strongly suggest that you investigate precisely and exactly what happened, historically, when ubuntu tried to do what you are forcing onto people in an unthinking and inconsiderate way. l.
