I will ask this more explicitly: how soon will you deprecate features in 1.0? 2 years? 5 years? 10 years? Go 1 is 6 years old and Go 2 seems at least a few years away, and the paragraph I was referring to says "Mixed programs, in which packages written in Go 2 import packages written in Go 1 and vice versa, must work effortlessly during a transition period of multiple years.", which suggests they will keep the Go 1 compatibility for "multiple years" after Go 2 kicks in. That adds up to 10 years. If Julia can promise to keep the vast majority of 1.0 features around for 10 years, I will be good with that.
