It's not. The Go 1 backwards compatibility promise means existing interfaces won't change. Take the Math package for instance: I'm not aware of any planned breaking changes -- if you are, please share. If they were to add support for non-int64 operations, they would likely be separate functions or a new package. This, without sweeping code changes, nothing changes.

The Go team has been discussing converting some functions to generics _if_ they can maintain the compatibility guarantee. Without verifying, I believe this was discussed in Go Time ep 216.
