https://wiki.ai03.com/ is what a lot of people use. Though it's probably easier nowadays to use an RP2040-based ProMicro form factor daughterboard so you only need to handle key placement.

As one of the QMK Firmware maintainers, it's great to see you're going ahead with the customisable side of things even on the input side.
Might I suggest engaging with QMK early so that we can avoid the usual manufacturer "hey can you merge this, we've shipped already and forgot to raise the PR until now"?

Just a heads-up, missing a few; https://golem.hu/boards/ seems to be a bit more complete.

None that I'm aware of. And I don't plan on running one of my own -- too many other things going on.
That said, I ended up creating a Discord months ago after a whole bunch of people were going to run their own GB, needed a place to "host" it... never eventuated due to the COVID logistics problem.

Not really; it's a case of soldering on the parts as per the iBOM:

Only a couple of parts are actually dependent on the side you're soldering (and are listed on the parts BOM), virtually everything else is aligned in such a way that it can be soldered onto either side.

I assembled mine by hand.
I'm not sure a lot of PCB assembly houses would like reversible PCBs.

At the moment I'd advise against it somewhat -- the silicon shortages have basically made the MCU and a couple of other parts unobtainable.
That said, I got mine from everyone's favourite PCB manufacturer: JLCPCB.
All the parts can be found on the BOM: https://github.com/tzarc/djinn/blob/main/Rev2a/Djinn-BOM.md

Full disclosure: I started my foray into split keyboards with an Iris.
...but it didn't have all the keys I wanted, thus the Djinn.

In a week or so, QMK will pick up a whole bunch of new support for pointing devices -- Djinn's open-source, so if you're keen you can swap a display out for a Cirque touchpad for instance.

Right now, none really -- it's a hardware enablement testbed, and really only shows a handful of information, such as Caps/Num/Scroll and what layer you're using.
With QMK we get a lot of requests for "how do I display this", "how do I show that", so it's more a case of making sure it supports most of those scenarios.
Sadly with the silicon shortages, not a lot of people are getting the chance to build them... I'm sure we'd see some interesting usages if/when this display stuff becomes a bit more mainstream.

Oh hey, that's me!

QMK requires a RESET keycode to be added to your keymap in order to reboot into firmware update mode while it's running. Alternatively, depending on the configured options at compile-time, you can either hold ESC as you plug it in, or hold Space+B.
system76's launch requires the holding of ESC on bootup (well, top-left matrix position).
Under normal circumstances there's no "unattended update" functionality built in. Unsure if system76 has modified this behaviour to do so.

Ended up designing a 64-key one with displays: https://github.com/tzarc/keyboards/tree/main/Djinn -- can't see myself going any fewer than that.
