Okay, but I guess this is where we're differing here. WP_Rewrite
doesn't call *anything* directly. That's not its function at all. It
doesn't decide what gets displayed, it's not a controller and it's not
meant to be.

WP_Rewrite isn't supposed to be a controller in that sense. It's just
a URL parser. That's it. All WP_Rewrite does is convert the URL into

Other parts use those query vars to determine what to do and where to
go. In particular, WP_Query uses the query_vars to determine what
content to pull out of the DB, and then it sets flags accordingly. The
template-loader then uses those flags to determine what template
(view) to pass control off to. Everything is nice and separated.

The "router" in WordPress is the template-loader file. Not WP_Rewrite.

You're trying to fit a square peg in a round hole here. Yes, you can
shave the sides of the peg and make an octagon to fit through the
hole, but it won't roll as well as a cylinder would. ;)
