I hear what you're saying, but it would still potentially be a big perk to a lot of people. It was talked about pre-roll out of FP+ but never happened. They could tier it too. 3 FP per day for everyone. 4 for value guests, 5 for moderate and 6 for deluxe. They could also roll out resort guest only FP. For example, they could only offer FP reservations for shows/parades to resort guests or certain popular meet and greets. I think if they got creative it could be a pretty compelling perk to try to get people on property.
Edit: keep in mind too that EMHs costs money to run while offering extra FP reservations is free. It's a big reason I still think this will eventually happen.
