I got a pretty decent number of quality comments on my blog post, and
they were unanimous - they'd prefer what the Cascade draft now calls
"cascaded style", where initial/inherit still show up, and if nothing
set a given property on the element, it returns null.  It seems to be
more useful for polyfilling purposes (for example, it would let a
library tell the difference between a custom property being set on the
element and it just inheriting a value from an ancestor).
