note: I'm not sure whether this is the best place to put this function. Let me know if I should move it somewhere else.

My suggestion is a bit more simple and somewhat different: GV.setLinkage and Fn.setLinkage should call GV.setVisibility under the hood, no need to involve visibility kind. If you make linkage into an interface, than you don't need to implement in both places.

Thanks for the comment! I was trying to do that in future PRs, but I ran into some issues when dealing with FuncOp (#1029 (comment))
