Thread:User talk:CodeCat/Reversion of my merger of the etymologies of "loop"

I was under the impression that the general consensus was to only separate etymologies if they were mostly or entirely different. While the verb may come from the noun, definition 2 of the noun probably comes from definition 1, and all the other definitions precede in some way from an original sense. It would be ridiculous to separate them out, however interesting it might be. Is there a reason you feel different parts of speech should be given distinct etymologies, and am I wrong in thinking there was a consensus not to do so?
