No.
This too - the current degree - shall pass. There will always be some trolls and some inexperienced, seemingly unaware but obvious to everyone else oversights, by new posters.
Sometimes even the most experienced start new threads, etc., when there was no reason to, simply because people use the board differently. (And sometimes, granted, there is no excuse). Not everyone is on here 24 hours a day. I saw some sniping earlier regarding the mega-thread that didn't take such differences into account, that not everyone is going to know the current state of the situation.
Sure, people can and should politely point it out, and people should read what they can first. But not every situation called for a rebuke or face palm.
I know though what you are getting at.
The primary reason I oppose is if someone new truly has inside information, for example, or is even a parent or coach of a prospective recruit, I don't think they should have to jump through this hoop. I don't believe the benefits outweigh the costs.
And +1 and lol on the upper limit.

Some I think need more self control. Repetitive points can truly drive other people away. Say your thing and understand that people got it the first time. Even if someone posts a counterpoint, the same can apply.
