I've run a couple MCC missions, and I don't even know how many hours of just testing the Bradley with JSRS enabled, and it has been fine.
Having said that, I have not done close to enough testing to give my opinion on the matter regarding using JSRS during OPs, so I with the CPT on this one, I just wouldn't use it to be safe.
But I would be happy to help test it if there is some kind of sanctioned testing process for some of the more questionable client side mods.
I'm also of the opinion that there isn't a client side mod out there worth it if it costs a good Operation server experience on Sunday evenings.
