I'm not sure I know what you are referring to when you say "such a feature" and "this". Do you mean putting the selector into the function itself is necessary, instead of using the selector to the left of the declaration list with a different syntax? Or the other way around?
I'm not suggesting the removal of any features, just an examination of the syntax, so that we can standardize on the best method, and get as many implementors as possible to converge on that. It is possible/probable that some non-browser implementations will have to also continue to prefixed versions of older, non-standardized syntax.

Let's leave XPath support to a different thread. This one is really about the syntax supporting the features that are already in the draft. The part you quoted is about where to put the selectors and other syntax for selecting the bits and pieces that need to be strung together.
