^Yeah, if the Feds didn't share the tech (transwarp or QSS) with the Klingons I could see them getting a bit ornery over it.
Course, you don't see the Klingons sharing cloaking tech with the Feds and I believe the Treaty of Algeron only stops the Federation from researching it themselves (which they've blatantly ignored on at least one occasion in-canon).
Yeah yeah, oh mighty, Roddenberry says it would be unFederation-like to use the cloaking device.
On the Soliton Wave, I think it was probably the only time I've ever heard of a guy being happy about possibly put out of a job. Geordi was positively gushing over the concept of being potentially unemployed.
