The issue isn't mixerctl so much as the backend representation that
mixerctl talks to.

There are two ways that this could be done: (1) in the backend mixer
stuff, which would have the advantage that the aliases could be made
to show up across all mixer tools, but has the same problem that the
backend representation isn't powerful enough; or (2) just inside
mixerctl. The latter wouldn't be that hard. The catch is that there
are a lot of assorted *ctl programs and they all intentionally have
the same mib-type interface. Adding alias support to all of them is
probably not so trivial. I'm not sure to what extent they share code.

But under the circumstances, it's probably a good idea.

In the meantime, if you want a quick hack, you might try something
like this:

  --- /usr/local/bin/mixerctl ---

   #!/bin/sh
   /usr/bin/mixerctl `echo "$@" | sed -f /usr/local/etc/mixeraliases`

  ------

and populate mixeraliases with e.g.

   s/my\.volume/inputs.dac02/

which would then let you do "mixerctl my.volume" or "mixerctl -w
my.volume=128,128".

But it's a hack.
