So ....no containment at the down-lighters for the building wire loops, ...really, ...OK , lol!!!
At a single 1 way one gang maybe, but that's not always the case is it, especially in hallways/porches etc!! The last thread on this subject someone actually posted a photo of a switch looped switch, it looked as if you would need to force the dammed switch plate back into the box. So not my imagination at all!!
What you may call a satisfactory answer, is not necessarily anyone else's! I think i've made my position just about as clear as i can, if you don't agree that's fine too. I'm not telling you how to wire anything, you've been in this game long enough to decide that for yourself.
