I'm not by any means the one who should be answering this question, but just wanted to throw the idea out there that perhaps such things are best saved for major version changes. Because it would require every user to rethink the modules they're using in their system config.scm (and possibly packages that aren't installed with "system" would have to be re-installed manually). So perhaps on Guix 2.0, 3.0, etc. is when it would be acceptable to do house cleaning like renaming modules.
Just a thought.
