What are you disagreeing with? That there are about zero new
implementations? Or that we should put these properties in the spec?

FWIW, I realise Servo exists. I wasn’t trying to suggest that it shouldn’t
be counted. I should have said that it is extremely unlikely that a 
starting-from-scratch implementation will only consider the canonical
W3C specifications and pretend everything else doesn't exist.

As for the prefixed properties, it’s not clear to me what criteria is
necessary for it to be considered essential enough to document.
e.g. -moz-column-count or -moz-animation.
