An alteration to the core grammar requires us to analyze all 400+ existing, proposed and suggested properties, including SVG properties, (there are actually 606 by my last count, but who is keeping track). We must determine if any of them have to be updated, altered or changed to account for this new primitive. Don't forget to multiply all the values that all those properties take and how they will be affected. This is an extensive amount of work and who knows what we might miss when looking at all the values that those properties take.

Is "move things quickly" really the priority? It seems like "have the
most intuitive syntax" would be a more important goal. Of course,
"don't break the web" is probably a more important goal still :)

FWIW, if we were to keep the currently proposed notation (more or
less), "var-" seems better than "data-" to me; I too see the potential
confusion between this and data- attributes in HTML, and data- doesn't
scream "variable" or "value" to me.
