RYR fuel policy is for them and the regulator to sort out - nothing to do with ATC... as said above, why should they not fly the full FP route?
If they start getting short of fuel doing so then thats not an ATC problem (I know it is in the short term but they (RYR) will soon learn).
That is of course as long as some limp wristed ATCO doesn't give them a short cut because they state they are short of fuel but don't want to call a PAN.
