I think there's no reason why there couldn't be a button to allow users to
easily set up loopback devices.
One thing to note, however, is that this is specifically a limitation of
PulseAudio. With PipeWire it's possible to directly link the toslink input port
to the system output using tools such as qpwgraph (yes, it's a Qt5/Qt6 GUI from
the same person who wrote qjackctl). With PW Plasma could directly do such
linking, which has the benefit of avoiding the extra latency that loopbacks
always cause.
One slight difference to note is that loopback also applies volume control
whereas direct linking will result in capturing at the full 100% volume. I'm a
bit unsure about the exact effect but it would likely result in Mac OS playing
back at whatever volume it's outputting to the toslink and any volume
adjustments needing to be done there (although maybe I'm wrong?). As such in
rare cases loopback might still be desired but it's definitely not required
like it was with PulseAudio.
