I have positive news on scheduling through EWR, at least for me personally.

After a year of watching the 6:40pm ROC-CLE flight be ridiculously delayed at least 50% of the time since CO scheduled it to fly EWR-ROC (dep 4:50pm, arr 6:10pm), they have finally done something about it. As of last week, the relevant aircraft now leaves EWR at 3:45pm, arr ROC at 5:07pm, then dep 6:20pm for CLE. Much more realistic - a whole extra 65 minutes for the aircraft to make it EWR-ROC-CLE and for me to still make a connection in CLE. I hate getting caught up in EWR delays when I'm neither flying to nor from EWR, and when my connection at CLE is certainly not delayed.

I don't know if it was deliberate, but ^ to whichever department is responsible for the change if it was. Means I'm now happy to stick with CO via CLE in the evenings.
