This was adequately discussed on jack-devel over the last 14 years.

It took a very long time for qjackctl to stop exposing the options that were not intended to be "exposed" to regular users. Finally this has happened, which is great. In the meantime, a lot of people played around with things that are now on the "Advanced" tab, and often got into trouble (which is partly how we gradually came to understand that they probably weren't meant to be exposed. Cadence did a much better job of *not* including these options from the beginning, which is one reason why people could often get JACK to "work" when starting it there.

And yes, the man page does not explain it either, just like the man page for most other *nix software.

Sorry, I think I'm having trouble with my mail reader -

I missed the second half of your reply - the part
 which logically proceeds to tell us which options
 should not be exposed.

    Open your jack1 code. Add shortened words to that effect on
      each experimental command-line option you want. Push. Done.

    QJackctl team then then adds an "Experimental" tab, and moves
      option items to it, that you marked so, or hides them completely -
      it's their decision.

    Advanced tab = "Yeah, you might need these."
    Experimental tab = "Hands off, fool!"

    Problem solved. Everyone happy. No?

                 Maybe there are other ways to get there.

                      I find that response surprising, unhelpful and
        quite wrong.

                      How can anyone discover whether they need to use a
        feature
                 if nobody
                      will tell
                      them what it does?
                      How does one become 'advanced'?

                      Say you have a poem and I have a tune.
                      Exchange them and we can both have a poem, a tune,
        and a song.
