I don't want to go too far down the "wasting resources path," because,
honestly, a kid playing videogames for a weekend will waste more power than a
maintainer submitting a couple of threads for analysis.

I've already worked on plugging in LLMs into summarization, so I'm not alien
or opposed to this approach. I'd like to make this available to maintainers
who find it useful, and completely out of the way for those maintainers who
hate the whole idea. :)

Best wishes,
