>You say that like it’s even remotely feasible at the frontier of mathematics and not a monumental group effort to turn even established proofs into such.

Is it really known to be the frontier as long as its not verified? I would call the act of rigorous verification the acknowledgement of a frontier shift.

Consider your favorite dead-end in science, perhaps alchemy, the search for alcahest, the search for the philosophers stone, etc. I think nobody today would pretend these ideas were at the frontier, because today it is collectively identified as pseudoscience, which failed to replicate / verify.

If I were the first to place a flag on some mountain, that claim may or may not be true in the eyes of others, but time will tell and others replicating the feat will be able to confirm observation of my flag.

As long as no one can verify my claims they are rightfully contentious, and as more and more people are able to verify or invalidate my claims it becomes clear if I did or did not move the frontier.
