Why would it be bad to turn into CPAN?

Is there a language packaging/install system with better infrastructure and range of code libraries? (Or is that bad, for some reason?)

Edit: It seems the semver module don't have much of functionality for running tests, keeping DBs of existing/previous libearies, sending feedback to module authors of install problems or show statistics about what O/S versions had problems? (And so on.) So it isn't really like the CPAN infrastructure at all...
