Unlike most ecosystems, just because a problem is obviously important doesn’t mean the Go team will solve it in a hurry. They don’t like to change their minds once they commit (exactly the property you’re looking for!).

Once rsc or equivalent has blessed something, you can rely on it being that way for a long time. Before that, hedge your bets.
