For someone not well-versed in language implementation details, it may very well feel random.

I've been using Go as my primary language for a decade, and the lack of generics on methods was surprising to me the first time I ran into it, and the reasoning not obvious.

Yeah. I'm not claiming they didn't back themselves into a corner here.

There's no theoretical reason not to have it, the reason is because of a random intersection of other design decisions... unless you're saying they made those choices fully expecting to have these restrictions on generics later?
