Hi Dion:

It may be "proper", but in no way do I see it as "less hard."  The (current) "proper" approach is fraught with complexity. The global nature of the regex's use have significant potential for side effects and must be handled in a plugin vs. a theme in order to support activation (i.e. flushing rules.)

I've written a lot of rewrite code for WordPress. I've run into lots of trouble with it (it's probably the most "fragile" component of WordPress that I've touched.)  And unlike the rest of WordPress, rewriting never really gets easier (at least not for me.)

I'm very much for following best practices but in this case I seriously question if the standard approach to rewrites really are "best."  But then you probably also know I have a trac ticket open to evolve the URL rewrite system[1] that I have been working on as I have had the time.
