David Baron suggested that transition-delay should apply to all properties.
I said that I supported that in principle, but was worried about implementation
performance implications, given that the default for transition-property is "all".

Stepwise timing functions would give authors even more control over when
discrete transitions occur, but only for single-step functions. I'm OK with
allowing this to affect non-animatable properties.

So I think we're left needing to add some words to the spec, and getting some
implementations.
