Just 1 use case (one of a few I have):
  - sound card {a} snaked to separate recording room
  - sound card {b} wired to local mixer, outboard synths and keyboards
(for post recording/mixing enhancements effects etc.)

Everything is already plugged in. No software reaching out of the box to
reroute cables.

... but I really don't think beating this dead horse is worth it.
