This is likely all true, but with resolution independent rendering,
it no longer applies. In the future, "px" is just a measurement unit,
just like "in" or "mm". Once the software gets this, it's perfectly
fine for web developers to ask for a "12pt" font. It just won't be
rendered with characters 12 screen pixel high, but with this value,
divided/multiplied with the screen dpi.
I can understand this is difficult to get swallowed. For 40 (or more)
years now, the rule was 1 pixel = 1 dot on the screen. A picture,
100px x 100px in size used to use exactly 100 x 100 dots on screen.
Now, this is no longer true.
To stir the mix additionally, there are many pieces of software
respecting resolution independent rendering and many others not.
Picture viewers still map one picture pixel to one dot on screen and
call this "100%". Font/text displying tools still shortcut rendering
engines and draw a 12pt font with 12-dot-on-screen character glyphs.
Some software considers 72 dpi screens (Macintosh monitors were
produced many years this way) as "standard", others won't work with
anything but a 96 dpi screen (Windows XP default setting). This makes
comparisons so difficult.
My personal hope is, this dust settles once people get used to set
their screen dpi just right: it is a measurable fact.
Then, they will start complaining a 12 px font is waaay to big for
phone screens ;-)

P.S.: There's no real need for an additional measurement unit besides
mm and in, so I'd actually prefer to see "px" going away entirely.
What a dream!
