Anyway, if one is using a compression fitting, pipe dope or tape is not

compression fittings where pipe dope was used on the joint by someone
who didn't know any better.

As long as you keep it on the threads, and off the ring, where's the harm?

Typically compression fittings are brass which are self lubricating and the
threads do not provide any seal.
