I gave some examples... Say I want to write a general purpose CSS pretty
printer based on DOM Level 2 CSS. I would need a DOM implementation. I
tried to write one and failed [1].

Even if it would be possible to implement the specification [2] suggests
that the implementation should not provide the UnknownRule interface. My
pretty printer would thus be limited to CSS Level 2.0 style sheets in
contrast to the intention of beeing a general purpose tool.

And, would you use a CSS pretty printer that drops all comments in your
style sheets? I would not.

However, to make a start, I need a Selector API that

  * is at least as sophisticated as [3]
  * is forward-compatible in a usable manner
  * includes support for CSS Level 3 Selectors
  * allows to query for the selectors specifity
  * provides access to comments as in e.g. a/**/b {...}
  * allows to query pseudo classes, attribute selectors, and
    pseudo elements for their associated element type selector
