I've no idea other than I suspect they practice on themselves a kind of intentionally muffled thinking: believe that they are trying to improve the regulations but cannot change anything until they are absolutely certain the changes will be safe and effective. This despite the fact they did exactly that in 2014 but allowed themselves to be corrupted by big business.
I suggest you write to the current lead on the regs, Sean Valoo, at this address: firstname.lastname@example.org. and ask him!
