Maus, as far as I know, there was no requirement for F-35B to have a thermal burden, 'no greater than that of AV-8 or MV-22'. The USMC's total commitment to F-35B therefore attracts an additional cost of bringing other USMC assets (MOB, LHA etc) up to whatever standards the the jet requires to effectively operate.
Interesting question. It would be very surprising (and an important omission) if the JORD didn't say that the aircraft should be Wasp-compatible, encompassing everything that such a requirement implies. (It wouldn't have to be rated against the AV-8 or anything else.)
It would have been another serious omission to fail to define the composition, as well as the size, of a STOVL runway on land. 3000-foot runways, even in the U.S. and Europe, generally ain't made of MIL-SPEC concrete.
