Switch at what granularity?

This seems like it would lead to massive confusion, esp. when values are 
set via the CSSOM or come from different stylesheets and suddenly "pt" 
means different things in different contexts.

If your real issue with #1 is conversions, then we could introduce 
"true" parallels of all the physical units.  But are there actually use 
cases for using true physical "pt", say?

I think #3 (as well as #2, actually) would be an authoring nightmare.
