[cssom-view] Unrecognized - request for more information

It seems that toward the end of 2009 Mike Wilson asked for a rationale as to
why the ability to access unrecognized/dropped rules via CSSOM was dropped:

There are currently several projects and shim libraries in exactly the
situation he describes in his defense for retaining such an interface...
Personally I am not sure that that was the greatest interface anyway, but it
really would be great to have something _like it_.   Does anyone in the
relevant W3C group have any feelings on whether they could get behind a good
proposal to reintroduce some means of accessing at least "mostly processed"
meta-information already parsed by the considerably better and faster native
parser - or would it be likely to be DOA?

It seems that this would drive CSS itself forward by leaps and bounds by
making it considerably more practical to use new features in a reasonable
time frame without unnecessarily complex gyrations by simply adding a good
shim.
