Sort of on the same wavelength, but I've always seen the commercial potential in Axoloti as a platform, and unfortunately I could use neither your or Johannes boards 'as they come' in commercial products.
Your board is better than Johannes' in that regard (because population is massively reduced), but I still wish there was no population of audio jacks or even placeholders for them on the board.
I even wish the Tsunami didn't have that USB power port, because there is no way on earth I'd supply any instrument that is not powered through a purpose-designed barrel jack. I'm well aware that a lot of manufacturers accept micro USB to be a physically worthy power-supply receptacle, but I'm not one of them and never will be. I honestly wouldn't dare put such a crappy power connection on any commercial instrument I might produce. USB is for data as far as I'm concerned, not power.
So I'm aware of how much you've put into keeping it unpopulated, but I'd still have to roll my own if I ever got into commercial production. To be honest, after playing with the original board and being frustrated with pretty much every choice of population on it, I knew that either it will just remain a hobby, or I am going to have to pay someone to decipher the schematic and roll a board to my own physical design, something I can reuse in every relevant product, and never needs to be redesigned.
Really frustrates me, so much so that I actually started designing rig that could help me depopulate the original board. The only reason I gave-up on it is for the same reason your board frustrates me just a little, that being, depopulating the board makes the board look like a cut'n'shove (botch job) and crazy as it might sound to some, it bothers me that someone would open-up a product of mine and find something that would look like a repurposed board.
I've got big plans, and the Axoloti part of it matters a lot, because once I get my head fully around it, and am in a position to have others freelance for me, there really is nothing to hold me back, or to stop me expanding at quite a rate. I know exactly what people want, have got it right year after year after year, am expert at marketing, and I'm not too shabby with Blender. So my company will certainly do well. I won't allow parts into a commercial product, that has been repurposed or even looks as if it has. I would be much better off rolling my own board from the very start than doing stuff like that.
Had Axoloti been completely unpopulated, that would not be necessary, so that's why any population of the board bothers me when such things as headers exist.
