In a thread elsewhere (mastodon, I think?) the idea of using a Copilot-like LLM as an assistant in removing code was suggested as * a way to use an LLM with less discomfort about model provenance (since you wouldn't be using anything it generated ) * a way to get over some user cynicism (waves) about whether an LLM usefully "models" the code.

Of course, at the time noone thought copilot could actually do any of that, but it was a few weeks ago and things are moving quickly.
