I don't see this as a given fact at all, firstly pixels are always
relevant, not least because all the HTML user agents have appallingly
bad image resizing abilities.  Then there's the problem of small
screen user agents, these obviously only sensibly need a raster of the
size of the screen, there's no point having a "wallpaper" bigger than
the screen.

In any case, with only Internet Explorer [*] doing rescaling of the
CSS PX unit on these high resolution monitors, I think the WHAT-WG era
browsers are a long way from doing it, and until then pixel size will
continue to be relevant.

Not for many use cases, they're both important, I think this is an
excellent idea.
