Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Personally I would rather get the M1 or A14 chipset than the A12.
Not trying to be a kunt, i legit wanna know what the dongle issue is? Dongles can be purchased for as little as a patch cable.
I don’t think the dongle itself is the main issue. More that when you plug it in that’s going to stop you plugging anything else in (like a midi keyboard or a power source). Obviously there are ways around that, but nothing quite as easy as a headphone jack.
Headphone jack is really useful in mini because it's in a very convenient place, almost in the corner. This makes holding the device in an ergonomic way very easy (horizontal or vertical). Also works great when keeping the mini in the pocket. It will be a big step backwards having to connect headphones via centrally placed lightning/USB port and also via an additional adapter. Also for the reasons @steve99 mentioned.
Or having to acquire headphones with a jack alternative. Because Bluetooth is out of the question - too much of a headache.
Here it is, SOFA (Sounds Obviously Fucked-up Audio) 👍🤟
