It would be really nice to be able to do things like this in RT:

If the former, then maybe a bit.
But the beauty of physically-based is that in many cases, you can take a model that's been textured and lookdeved and it will work nicely in many different lighting setups. Before Physically-based, you practically had to re-do stuff completely when you changed the lighting to get the look you wanted.
However, Physically-based still isn't a complete win - you can't looked something close up and expect it to look good in the distance - it just won't. You need to be aware of the LODs and create different asset variations appropriately for different distances.
