Re: [csswg-drafts] [css-values] Ability to address actual physical size

@tabatkins I strongly disagree …

> "real physical units" are (a) impossible in general, due to needing every part of a hardware chain to reliably tell the truth about its scaling, which they don't do

This is not “impossible”. There are many hardware/software chains already in existence that do this properly (e.g. native Windows apps have been able to report/address physical display properties for some time now). And the places where it doesn't currently happen aren’t because it is impossible, only because it hasn’t been done yet – not surprising if there is no standard for it yet. It is a chicken/egg situation. The “impossible” excuse is like saying something like the new font variation features should be abandoned because some environments don't support them yet.

> and (b) very, very rarely, if ever, what you actually want. The one use-case that kinda makes sense (making sure touch targets are sufficiently large in real terms) is better served by addressing that directly with a 'touch' unit or similar.

So you are ignoring the entire world of print design? Accepting your statement is accepting the concept that no CSS for printed documents will ever be accurate or dependable. And accepting that is betraying the original idea of CSS.
