Maybe I’m misunderstanding here, but it seems like we have no particular reason to suppose P=NP is independent of ZFC. Unless it is independent, its probability under this scheme must already be 1 or 0, and the only way to find out which is to prove or disprove it.
I think shminux is talking about the possibility of future research addressing bounded reasoners, who could be uncertain of P=NP even if it followed from ZFC.

I fully agree that is an interesting avenue of discussion, but it doesn’t look much like what the paper is offering us.
