That sounds entirely reasonable, as long as people can choose to avoid the python package with its attendant variable-binding problems, if they favor reliability over convenience. A nit is that sometimes we have 1 version, and then 2, and then back to 1, and I don't want us renaming back and forth. So once we go to two, if we move to one we should stay with versioned names for perhaps 3 years before renaming. Overall, this would be a policy shift from how emacs is named, but I wouldn't mind it happening.
