I agree that one should avoid forking RT unnecessarily. While I still think that the current behaviour is flawed, it hasn't been an urgent concern since I've addressed the performance issue that acted as a trigger in my environment. If it were, I (as a non-paying customer with correspondingly low support expectations) would probably either come up with a fix of my own or migrate to different software.
I'd rather not be the one who brings this up in upstream's forum, though, as they require prior registration. But anyone else who feels this is worth pursuing is welcome to do so (and hopefully improve on my analysis: I didn't expend all that much thought on it).
