I would say structural typing is very "esoteric" for most strongly typed languages actually, but this is not a problem.

And proceeding, the implications of your response is very strange. See, your point is essentially saying that "we should use Go, because it entails writting in only one idiom, and writing in languages that enables you to do more idioms -- more powerful languages -- is bad faith to other developers", but Hejlsberg himself said he chose go because of specific characteristics of the compiler that was already written, not because it is "the ideal one for every single prospect", while your point has implications that are absolutely more general. So I don't think he would agree with you that this was his reasoning for using go (the "don't have other idioms" thing), I also don't think this whole "more idioms" thing even make sense, but this is not needed to respond to this.
