esprehn has just created a new issue for https://github.com/w3c/fxtf-drafts:

== [geometry] DOMMatrix should not depend on the CSS parser ==
I do not think the low level geometry types should depend on having a CSS tokenizer and parser available.

The spec does not provide affordances to parse any other CSS syntax, for example `rect()` into DOMRect, and parsing CSS is better handled by the Typed OM spec which uses an operation list to represent transforms instead of a matrix (which is a better fit for CSS anyway).

If authors wish to create a DOMMatrix from a list of steps they can do:
  new DOMMatrix()
which will also be faster since it doesn't require parsing all of the numbers back out of a string.
