Ended up attaching my dongle to my headphones with a Velcro cable tie after forgetting it one too many times (I need to take it on and off all the time to connect it to my Mac, as it doesn’t have a Lightning port - the fact that that situation exists feels like an omen that Apple aren’t quite firing on all cylinders). It sucks and looks stupid but it kind of solves the problem.
I wish they’d not removed the port, it’s a real pain and I’m not willing to go wireless until there’s a way to do it with zero latency. I’ll be really disappointed if the new iPad removes the headphone socket as it’s pretty essential for music making on the go.
