* have no changes to be made from Go 1.n other than backwards-incompatible ones, or
* would have no backwards-incompatible changes at all.
I get the feeling that the developers have learned a great deal about not making large breaking changes & segmenting the language.
The Go language accomplishes some amazing things so far, and it a pretty decent choice in the systems-programming space. Even if google dropped it, there would almost definitely be another company or group willing to be it's benevolent dictator(s).
Can't speak for Angular, but in Python land, ~9 years later, people are still cleaning up the fallout of the changes from Python 2 to Python 3.
It wouldn't bode too well for such a young language as Go to go through the same process.
My personal observations are that Go is gaining a lot of steam in many places. Announcing that they will break compatibility would make those places strongly reconsider their commitment to Go.
Umm, they've actually announced the opposite. Not sure why you say that.
As in, if in some hypothetical scenario, Google announced that they would break compatibility, it would be bad.
