TV use-cases seem like they'll become more prevalent, with Apple and 
Google and their devices.

I could imagine that some window managers might introduce strange 
pixel-bending effects; but that's just imagination.
I don't think we can speculate that much on output devices of the future...

In any case, I think we're just talking about limiting the scope of 
support to exposing an X and Y ratio, instead of just exposing a single 
value. If the scope goes further, yes it may be a waste of time. 
Otherwise though, I think it's more a concern about 
precision/conciseness than it is about an investment of time/resources. 
That said, display technologies are over my head.
