The simplest way for Apple to address this problem is to update the free Lightning charging cable included in the box with a pass-through port on the plug, adding no more bulk to the cable. Third parties will certainly be able to crank these out pretty cheaply as well. Personally, I'd opt for a $20 BT dongle for my car's head unit, that I could also take with me to use in other cars, airplane entertainment systems, house parties, etc. But that's me.
When your battery runs out, you plug in your cable and keep listening. Don't buy a pair of wireless headphones without a detachable cable.
That's anecdotal evidence at best and from a very specific demographic . Here's a survey that demonstrates very different results.

You're right. By the time USB-C achieves any kind of market saturation, the Lightning port will likely go away completely on the iPhone, and wireless will be the only way to connect anything to the phone. If someone absolutely needs to connect something physically to the iPhone, it will be through magnetic induction. Most other devices will provide a standard wireless interface as well. Since USB-C won't eliminate the need for adapters for well over a decade, carrying an adapter after wireless becomes the standard won't be a problem.
I'll guarantee you they've given more thought to this than you have.
The simplest answer is you'll need a splitter, which you'll leave attached to your midi keyboard. I can imagine other options, some included in the box, depending on your headphones and equipment.
Out of curiosity, how do you charge your iPhone currently while your MIDI keyboard is plugged into it? If you're like me, a long music session could easily drain your iPhone.
1a) If you want to keep using your old equipment, yes you will need an adapter and I expect Apple will not include one in the box. Expect to pay $20 for one.
1b) of course your Lightning headphones will be compatible with any Lightning port. If you have an old 30-pin iPad, you'll need an adapter. I expect Apple will add Lightning ports to new Macs. But you'll need an adapter with your old Mac. The difference here is that I don't expect this adapter to be very expensive at all.
I expect Apple to update MFi specs to allow analogue audio to be input through a Lightning plug for use with an analogue device -- a situation that hasn't existed before. Since Lightning is a smart connector, a chip in the adapter will tell the headphones to bypass the internal DAC and pass the analogue signal straight to the transducers. This prevents the ridiculous situation of converting an analogue signal into digital just to get it into the headphones, only to convert it back to analogue again. Such an adapter could easily be less than $5 since it's basically just a conversion wire. And I expect Apple to include it free in the box, as it promote the use of Lightning headphones.
2) if Apple switched to USB-C, over half-a-billion customers will have to throw out their investment in Lightning cables and accessories over the last 4 years, and replace them with USB-C, which is not presently usable on much else. It will take several more years before USB-C is even widely available on many devices. by the time USB-C achieves market saturation, Apple will likely be removing all ports from the iPhone and go wireless for everything on mobile devices. And since Apple is promoting wireless headphones, which is a much wider standard than USB-C (which is in its infancy), there's no real reason to jump onto a yet to materialize wired audio standard.
Ask Siri to provide you with a reminder. But I can't help but observe your complaining about charging the headphones once a week, but not the daily grind of winding and untangling cables between each use, constant plugging and unplugging, and general cable management of using wired headphones. I have happily left that hassle behind, in a trade off of charging my headphones once a day, along with my other gear.
Nope. They just won't have wires.
