ERR is basically drop in. It's a matter of your skill to do the dropping but there is basically always a way to do it.
I think the interoperability in 2rail O/HO is nice. I guess I just never had/hear about trouble running anything from the four 3rail O scale manufacturers (Atlas, Sunset, Lionel, and MTH) so it never crossed my mind.
I'm still a little lost but I think I'm overreacting because I'm sick of the sky-is-falling talk on the news, in general conversation, and now here. I'm not one for getting stressed out or being serious when I criticize peoples opinions but I'm about at the end of my patience with this New World Attitude.
