No worries! As mentioned, we already have a proposal. Eight years ago
Nick encouraged me to write proposals for things I'd find helpful, but
of course a proposal doesn't magically turn into engineering
resources. We all have things on our plate, and there's no point in
spending time writing proposals unless it's gonna turn into something.
