I would rank them mostly unused. There was a point someone made in the past how choosing between design patterns is the equivalent of choosing calling conventions for functions, I don't remember the source, but I agree with the comparison. Most of these are superseded by struct and interface composition, along with general interface use. I've recently seen a factory in Go, it was rewritten into explicit declaration and this simplified the code. The visitor "pattern" is just a function that gets called for a traversed composite structure like a list or tree (see filepath.Walk).
