One explanation for the disdain of thread tape I did not see mentioned.

When tightening down a taped connection, the threads can cut the tape into tiny bits. If this debris manages to get inside the system, it can interfere with the regulator, block the needle valve, etc.

With this warning in mind, I have on occasion used thread tape on non-compression fittings, and gotten successful seals. I did make sure to leave the first couple of threads untaped, reducing the possibility any debris would immediately get loose. And when refitting, I was very careful to clean up every bit of previous tape. Which was a royal pain in the arse. It's really better not to use it.
