As a small correction, “You’ve performed this action too many times” in the admin dashboard is not new. It used to occur for me every now and then, I forget how often but it wasn’t enough to be an issue. Also, the community health page is unrelated to the Reports tab.
In fact, I just tested it on my test site and it didn’t 429 until I alternated about 5-10 times. Rate limiting has historically not been very customizable but are you sure you just aren’t clicking too fast?
Shortly after it stopped giving 429s entirely..
