I proposed it when it wasn't clear that resolution meant the same thing.
Now that it does, and given a little time to make sure implementations
get it right and implement dppx, I think evangelists, tutorial writers
etc should switch from teaching device-pixel-ratio to teaching resolution.
Hopefully, authors will follow before long.

I am also toying with the idea of adding an informative note to CSS Media
queries (level 4) explaining how to map -*-device-pixel-ratio to
resolution.
