There used to be a stated somewhere on Mersenne.org the potential for an award for those who made a break through that speeds up GIMPS search by some amount (5 or 10%.) I glanced over at
https://www.mersenne.org/legal/ and could not find it. I think that it was pulled a while back.
I think that the recent developments on the PRP verification front are something that the board should consider at their next meeting. Perhaps an award could be granted.
