Hooray! I'm curious to see what you come up with.

I'd like to not have to re-implement the Link interface if I'm just
going to change the url or add query parameters. Currently LinkImpl is
in internal.services so if we could get that moved, or add setters to
Link or some other strategy.
You've probably only given a piece of the interface, but to be sure:
For incoming URLs that have been rewritten, does
ComponentEventRequestParameters make sense? If I've totally remapped
the URL tapestry is going to have a hard time putting anything useful
in there.
