I spoke at length with Shane at uAvionix today and got the info I needed. The MUX is not required, but can help resolve some situations where you might get failed reports.

Specifically, if you fly a lot in rural areas, class G airspace, or places where you might not get much in the way of radar coverage, or other aircraft interrogating your transponder or ADS-B much, you could see coverage drop outs, or at the very least BARO issues because you're not sending out recent pressure alt from your system. This can also happen if you're down low level a lot.

Where I fly mostly this is never an issue, so I'm going with the EchoUAT and Sky-FX-EXT and no MUX connection to my GTX 327. The nice thing is, if I ever need to add it, I can do it.
