That's not true. Not making different versions for different DPI doesn't
mean DPI differences can be ignored completely. E.g. buttons need to be
big enough for the highest DPI screen so you can push it with the thumb,
but that buttons will look ugly and huge on a low DPI screen and super
easy to click on with the mouse. Thus you cannot really measure whether
buttons are big enough without actual access to the device's screen.
You seem mixing up "Taking DPI into account for multiple versions of the
design" with "Taking DPI differences between the design target and
design test machine". That's not the same.
I've done work on touchscreen adoption of various parts and touchscreen
cabbie ports so I can tell you that you need to consider this, and that
testing the design on the actual device always reveals some flaws that
weren't visible on the sim.
That said, ideally we should also take DPI into account in the code and
themes (so multiple versions for the same resolution), but I'm afraid
that's not feasible because we have too little developers interested in
