Might not be an entirely bad idea to restrict EWR to the use of the primary runway. It is frequently a goat rope when the crossing runway is being used for arrivals. Having been sent around there and observing the flow, it is a place where you're fingering the TOGA buttons all the way to the flare. Then going missed off a visual seems to always confound the controllers, although you think they'd be ready for the question.

The RJ's have not been an issue as much as the biz jets have. I can understand the controllers' issues with sequencing when a Citation does 100 knots all the way in and a Falcon driver holds max forward warp until short final. Having flown 91 and 121, there is a huge variance in the profiles that those aircraft and pilots fly.

They don't have to "close" the airport to part 91 at certain times of the day, but 30 minutes of holding for sequencing will send the message that Teterboro is a "more convenient" destination.
