Yes, as I noted in the doc (but need to emphasize), I'm not intending to
describe day-to-day patch review here. I'm thinking more of larger-scale
discussions such as "Introducing Rust into the Git project" [1] or the
spinoff discussion "Defining a platform support policy" [2].

While clearly nothing has been decided on those topics, it seems to me
at least that they follow a pattern of "discussion now, consensus
(hopefully) soon, implementation later".

Or do you think it's more accurate to say that we rarely/never make
decisions without patches? Does that mean it's pointless to start a
discussion without a patch series attached? I'm trying to decide whether
it's worth editing this doc for V2, or just starting over with a much
smaller one instead.
