I suspect the reason it hasn't been discussed before is that there are 
an unlimited number of things we can do to improve the Web platform --a 
list of things that grows and changes rapidly-- and a limited number of 
people to specify and implement them... and those people often disagree 
about what the right thing to do is.  Sometimes you have to step back 
and take a holistic look at the platform and identify what's missing, 
and what has changed in priority.  Though I differ with your 
conclusions, I think your questioning of these new form controls has 
helped highlight an important issue... how do we style these elements 
and their pseudo-elemental components?

I think that a careful examination of the common constituents of these 
controls would give a lot of power to designers while still allowing for 
innovation by browser vendors in rendering them.  For example, you 
showed 2 different styles of slider, one with tickmarks and a 
rectangular thumb and the other a simple bar with a round thumb; a 
designer could still change the color of the thumb and bar (and maybe 
things like rounding of corners) and specify the color of tickmarks if 
they happen to be present on that platform (or to hide them if they so 
choose); I alluded to this in my earlier email that kicked off this 
topic of styling native controls [1]... if no tickmarks are normally 
rendered, that pseudo-element rule simply won't be applied, and that's okay.

It may have occurred to me more readily because, like a lot of people in 
the SVG developer community, I've been rolling my own SVG controls for a 
decade or so, in several different libraries, where each component 
(slider bar, thumb, tickmark, labels, etc.) is a distinct element, and 
thus easily styled.  People who create HTML equivalents out of <div>, 
<p>, etc. have a similar experience, I imagine.  I see ARIA as a real 
boon for these custom controls, especially in SVG where we never intend 
to have native form controls, but I see equal need for CSS to afford 
native controls the same kind of stylability (and I'm glad to see that 
some browser implementers and CSS WG folks are amenable to that).
