@ToddWilcox: trying to find that data on SO where I saw it once, years ago, about new users who wouldn't interact again after a massive DV on LQQ, closed-question or right after an answer (1 question / 1 answer / never return). Couln't write the proper request on SEDE either to extract that kind of data, if possible anyway (this, I don't know)

@ToddWilcox: I can understand that many users didn't want to open what might be a Pandora's box. Doing so, I hope I didn't harm the community by pouring oil on fire, just did what I thought was right. It doesn't mean others are gutless :)

@NapoleonWilson: my bad... my answer is mainly about the notification (1st part of my answer) and only then (last paragraph) about the question asked by @ galacticninja. But I thought we could kill 2 wraiths with 1 stone :D

To me: low-quality= yes. Low-effort = no. But that's not really the point here and at the moment. Also, let's not point finger to a potential writer, it's not that important, but rather focus on the agreement to modify and the final draft of the notification. Seems much more important to me. We'll reach an agreement by discussing the points and giving arguments for the pros and cons.

"whether overturning an existing policy based on little evidence, or maintaining a policy based on little support is the worse evil.": you're so d*** right sir! :) There will be (un)happy people no matter what anyway...

@galacticninja : "Close reasons should have something to point to (a meta post...)..." -> this can be collectively written I believe.

@Randal'Thor: the then policy, even that old, shall stay as is (in my opinion). My recommandation of writing an email was merely a humoristic 2nd degree attempt at saying "I like his points and arguments." I hope he probably hasn't changed his mind though. But his 12 years old arguments still seem good nowadays.

"find an absolute bottom limit in order to keep the reasonable ones open": that's the problem. Lowering the threshold to get more. Lowering the quality to get the quantity. Lowering the quality to have more fun. To get more rep. That's not what we should aim for... Better one suit from Savile Row than a full wardrobe of Shein.

"the moderators didn't actually need to stickle him on behind the scenes to ask this." (him being me, the writer of this): I can confirm that I never ever had direct interaction with any staff member or moderator of this stack. I initiated the above discussion because there were multiple comments on the main site, and I was kind of fed up with this 'no give no take but pull the rope'... Still am though :)
