Yeah, Python tried this as well with their 2to3 tool (https://docs.python.org/3.5/library/2to3.html), but their release bump was a little bigger than the Go prerelease changes (and the users not as flexible) so it wasn't much of a magic bullet.

I find it very useful but it does help to write forward compatible 2.x code and test frequently with 2to3 to catch what it misses.
