This is fine.  Each spec that adds new properties just puts a little
IDL section with this in it:

partial interface CSSStyleDeclaration {
  attribute DOMString? newProperty;
Amend the table at ... to contain the following additional rows:
| newProperty | new-property |

It's pretty trivial.

An alternative is just to hack around WebIDL here, and simply state
that the interface has a number of additional attributes of this form,
which map (as specified) to the CSS property obtained by transforming
the name by <specify camelCase to dash-separated>.
