Re: [csswg-drafts] [css-fonts] Proposal to extend CSS font-optical-sizing (#4430)

>> I was suggesting that _if_ we were to redefine the unit scale of the opsz axis, we would need to more precisely define it than CSS px seems to be defined, and in effect that means locking in a standard viewing distance, such that one could say e.g. the unit is 1/96 of a standard/industrial/physical inch

Right, that's exactly what I think is appropriate. 

> Scale interpretation: Values can be interpreted as text size, in points.

Becomes,

> Scale interpretation: Values can be interpreted as text sizes in 1/96in. Values can be converted to Points (1/72in) by multiplying 0.75x.

And,

> The scale for the Optical size axis is text size in points. 

Becomes,

> The scale for the Optical size axis is text size in in 1/96in. 

If this redefinition of unit scale is made, is the original proposal required? I believe yes because on some systems it is ~1/72in or ~1/54in and CSS authors want to adjust it.
