Despite the potential awkwardness I have to wonder whether this would even help us with the goal to speed up the overall process. To me it rather feels like there's another step now that a patch series has to go through, so my naive expectation is that it will rather slow the process down even more.

Am I missing something?

True. The other problem I see is that it might also skew the rate of patches towards subsystems that have more active contribtors (or rather subsystem maintainers). Other subsystems that don't have the luxury would then potentially be disfavored.

I guess this is especially an issue as the most active subsystems tend to be the ones maintained by hosting providers like GitLab and GitHub. Drive-by contributions on the other hand tend to be more cluttered around different parts of Git, and here it's unlikely that we have enough people to serve as subsystem maintainers.
