Probably not really in an issue in this case, though. After looking at it some more, DestinationParser isn't really relying on any code in Rails, its relying on consistency in the routing API going forward. i.e. if Rails stops supporting this format, DestinationParser won't break, but the concept won't align correctly with Rails any longer. In this case, I think we're OK.

Yes, it's not doing any more than "route_to" is already doing (ie. preparing the parameters to be fed into "assert_routing"). It may have looked scarier than it was; I just wanted to stick it in a module so as not to repeat the code in each of the three matchers.

Yes, would be good. To be honest, with a change like this (involving interface design), I think slowly is the way to go.
