My biggest reason for not wanting to canon to ever change Jason clawing his way out of his own grave is, aside from the sheer horror of it, it's so important to me that Jason's resurrection be seemingly pointless.
Because then "why can't Jason move on now" is answered with "because he wasn't supposed to have this chance and he knows it". It's like survivors guilt, where you are both the victim and the survivor. He shouldn't know why he's alive again, he should just know that if it weren't for some cosmic mystery, he would still be 6 feet underground while his killer ran free and his family told themselves morals about his death while he was voiceless - helpless to have a say in his own narrative.
My ideal Jason isn't necessarily a Jason's who's right, but a Jason who raises necessary questions. Jason as a constant scream of the forgotten victims of rogues, of those who are failed by every sytem, and responding with a desire for blood and vengeance and a brutal justice. Jason haunting the city.
