Ok, I tried it, and as I assumed it had no effect apart from stopping SMPlayer playing through ALSA at all. I'm guessing this is a glitch in SMPlayer, because MuseScore plays fine through ALSA and makes the ALSA-Jack client appear. This solution still seems functionally identical to my ALSA loopback setup - most things work fine but Firefox still creates a "Firefox" Jack client and outputs through that instead of the default ALSA device.

Also, this deviates from the point I was trying to make in the first email - Jack's system ports can't currently be hidden from programs, and it would be useful if they could.

If you don't have the plugin then just get it from your distro.

I posted a solution to your problem, one which actually works
since I've been using this for the last five years or so.

You respond by posting something that starts by saying that
you don't understand it.

I'm not going to waste any more time on this.
