I think the simplest way to get it to stop with this kind of thing is to just instruct it that framing constructs are strictly banned, and then giving it a few examples like the classic "it's not this, it's that". Qualitatively it seems like lots of this "load-bearing" stuff actually falls out from the framing, and as Claude would say, the problem "dissolves" once the framing goes away. I do wonder how this affects reasoning, if at all.
