I do feel the pain here, though it doesn't seem like enough of a
problem to overhaul the language the way that many (all?) of the
"distributed extensibility" proposals do.

I suppose it's too late to change "data-" to "d-"...

I'm not sure I understand the distinction. Is the distinction
attributes defined by the UA vendor, vs. attributes defined by the
page author? Or between attributes defined by a library author and
attributes defined by the page author? Or something else?

Again, I'm not sure I understand this. It seems like basically all
proposals use some sort of prefix. Some shorter and registry
protected, some longer and uses collapsing mechanism (xmlns, CURIE) to
turn them to a shorter prefix.

That sounds like a good idea to me.
