The maintainer is typically not the assignee so if you e.g. merge the last patch on Thursday afternoon it takes some time to gets attention, in the meantime there is a build which won’t consider that bug.

it is when the amount of false positive ON_QA bugs is far less than amount of forgotten bugs
I’m not advocating for it, I’m just saying it was pointed out that this was the situation before we introduced the hook.
Perhaps with the doc police emails it is no longer a relevant point
