Sure, if one of its dots makes one pixel.

I didn't say it was a particular good idea to use 'px' for any media but 
'screen', likewise it's not always sensible to use metre-based units 
(incl. 'in' and 'pt'). I just said it had not been a good idea to define 
the pixel differently than common expectation and true angular 
measurement would have been better, though unusual. I don't expect the 
definition of 'px' to (substantially) change anymore, but 'deg' etc. 
could still be introduced for lengths.

That's totally what I had in mind.
