Disable drafting of people who don’t have a power reading

I was thinking of ways to improve racing in the “a” category and one thing that occurred to me was if during races people who had no power were undraftable by everyone else it would solve a lot of the problems with fliers. They should allow them to draft everyone else but remove their draft ability then filter them at the end of the race. This would bring the pace down and make things more realistic in the peloton.
