@frlan could give his opinion, but I agree with @elextr : the plugins themselves are the responsibility of their maintainers, not really @frlan that can't know them all inside out anyway.
And as a maintainer, although I am fine with people merging stuff to plugins I maintain when I clearly don't have time (which I clearly don't 😅), I'd still rather review and merge myself when I can so I know what I'm maintaining kinda.
The only gray area would be quality control as the bundle is kind of a whole expected to behave, but we didn't have this kind of problems in the past I think (but for the unfortunate yet expected bugs that will sneak their way in no matter what anyway, but none of it was gross negligence nor malice), so I don't think there's any reason to be rigid in this area yet.
