I don't know of any plans, but hyperref actually adds to url.sty
rather than providing a new command.  The relevent part is
\hyper@normalise, and putting the following [taken more or less
directly from hyperref.dtx] in your document seems to work [but
probably renaming the commands defined would be sensible], but I've
not read/tested it especially well...
