We, as a project, need to set better criteria for this. Right now it says "has made enough contributions" which I confess is a cop out. It's very easy to "game" metrics like this, but "you know it when you see it" is just as easily abused.
I know Keith has been super involved in a lot of discussions of very complex things. Does that count as "enough" to be a full maintainer of the project? I don't know, and I am not just trying to be polite. We don't have criteria. At this early stage, "contribution" is super vague.
We don't yet have OWNERS files (yet!), which I think would help anchor this discussion. Even if we don't ENFORCE it yet, it captures intentions. Github CODEOWNERS is a hot mess, IMO. Is it worth establishing some OWNERS files?
We have all been busy and so this discussion has been postponed, but it has to happen eventually (and soon).
