The issue with deck heat comes down to the auxiliary power unit (or whatever the military guys call it) as I understand it. In the F-35 that points down rather than directly out back. So any hold position or other position that has the location of the exhaust point relatively stationary must take that into account - continual exhaust heating up a very small area.
Or at least that was something that had to be incorporated into the design of holding areas for land based aircraft. The RAAF use tarmac for cost reasons, the holding areas had to be concrete for the APU reason given above.
