Oh, Perseverance.

Yes, I never found a reason to take that over the many other traits on offer. It's way too weak, first off, and thus would require way too much investment to be useful. Secondly you don't get frozen or petrified all that often, if ever, so it will almost never be useful. Except if your Godwoken is a Dwarf and you're playing a very niche build that petrifies itself and regenerates armours.
