I don’t think there’s much we can do about this one without a big change to how we use the explicit routing.
It will likely get easier once there’s nothing that needs to fall through to the old site. At that point we might be able to control it by just the cookie.
We haven’t run for a good while into 404 errors served by the legacy site, so this issue can be marked as verified fixed.
