In the spirit of "bipartisanship," I can honestly say that people who previously got fewer than 3 FPs (in some cases none) will probably like being limited to 3 FP+ because that's 3 more than they got in the past.
Also, first time visitors may not perceive it as a "limit" of 3, but rather a benefit that they are "guaranteed" 3 rides with "priority boarding." If your expectation is that you will have to stand in line for all of the rides, getting to "skip" 3 of those lines would be an improvement.
For the record... NOT sarcasm.
