I haven't heard of this proposed change, and I'd be surprised if it's going to be coming into effect anytime soon.
But I would be in favor. Yes, it introduces a bit more luck into things, but it would go both ways - server might get a lucky ace that hits the net cord and dribbles over, but would also get more faults on serves that hit the tape and take a large hop out. Anyway, we accept this kind of chance on groundstrokes that hit the tape, so why not treat the serve the same?
This would save arguments over let calls and take subjectivity out of it, which is a good thing in my book. As other have pointed out, this is the rule for college tennis, and they seem to be coping with it just fine.
