Yep, I can just avoid using one of the keys, I just haven’t seen many key maps with the sort of popularity that Miryoku has, and I hate the analysis paralysis of trying to decide between 10 comparable keymaps (or trying to build my own from scratch).
The issue with TRRS is that you can easily damage your controller(s?) if they’re powered while the TRRS cable is either unplugged or left in a “not quite 100% plugged in” state, as the metal contacts in the connector create a short (between data and power IIRC?) when mid-way plugged in.
I recently fried a controller this way because I didn’t realize that the TRRS connector had gotten slightly yanked and was ~90% plugged in, creating a short, and the controller has been busted since.
In general the advice is “never plug/unplug TRRS while your keyboard is powered” and “always check to make sure TRRS is fully seated”, but in practice it’s easy to make a mistake that requires replacing your controller (and desoldering it if you didn’t socket it, oops).
I like the T-34 layout[0] - I like how much 'science' (research) did he put in it. An another one is the callum layout[1].
There is an option with QMK to rediscover TRRS cable when it gets disconnected or is plugged after startup, but I see now that that's not the only problem. TRRS is an easy/cheap solution, but a dangerous one if not correct.
