Ack, yes I'm very grateful for Roman's work, I think it's just a question of
figuring out how to fit things into our workflow effectively :)

Going to be a (possibly) bumpy ride but in general LLMs are _very good_ at this
kind of thing (code review, diagnostics), so it's an appropriate use of them and
in general I really feel we can catch a lot more bugs a lot sooner this way.

So, obviously modulo expressed concerns and details of how we do things, I'm
very much excited by and in favour of using AI for this kind of thing.
