Since we moved to chi, we do not have dependency to macaron anymore ... ( @zeripath you talked about some "cant do because of macaron...", can you describe these if you remember?)

also we do use context package more heavily, we should have a look what we could optimize there.

• look at https://gitea.com/go-chi/ and improve/refactor all of it (now we dont have to care about breaking changes)

Our route code has been hugely refactored by #24080 , I think there won't be blockers, we are on our own way.

So this issue could be closed?
