I'm not sure Matrix or EF is really required. For instance, in the case of V, it can be communicated to this person that if Flex is unavailable, or shows a M, U, H, or Q fare, the FP isn't available. For business, if the website is selling Business (lowest) in D, Z, or P, it should be bookable.
Oddities of the FP system could still generate different results when booking, but that's also true for EF or Matrix.
