Okay good :)

What's wrong with using CSS (aka Device Independent) px as that unit?

1 CSS px = 1/96th of 1in

1 CSS pt = 1/72 of 1in

Browsers are entrenched with mapping opsz values to the former. 

That's the fact. The ot spec needs to be updated to match this reality. 

Non px systems need to convert opsz values to pt; they don't exist yet and aren't entrenched.
