There's a misunderstanding here. I was pointing out that if the OP
wants volume control on a stereo output he'll have to manually add
one using a plugin or standalone jack client that does that. It's
something I've been doing for years (and the purpose for which
zita-mu1 was designed). The additional pair of connections has
never caused me a problem. (Note that I'm talking about a single
stereo monitoring output here, not suggesting adding a plugin on
every hardware output).

My analogy with a hardware patch bay was purely to help the OP
visualise things, not an approval of arbitrary restrictions.
