As long as Physical Ranged exists within its own role category, there's no incentive for the developers to give it parity with Magical Ranged. It will continue to languish under the claim that it only needs to be balanced within its own singular protected slot.
For reference, in Heavensward, Ranged was treated as a singular role category:
Patch 3.1 Notes
That was also the time when Physical Ranged was at its most powerful, and double Physical Ranged comps were in vogue. When it splintered off into its own subrole, it ended up doing less damage on the claim that it was more 'support orientated'. But Magical Ranged on the whole offers much more utility options, be it in the form of raises, defensives, and even burst mobility. So we shift the goalposts, and it now does less damage on the claim that it's easier to play and allows free movement (which is irrelevant, because burst mobility is what matters). I think that's why we're seeing more discussions around
walking casts now, because players want to see a more level playing field between the two subsets of Ranged jobs.
Merging back the subrole would force balance adjustments across the board, both in terms of damage and utility, and let Physical Ranged jobs feel valuable again.
