Our configs/ directory is also growing, so we could think of using
sub-directories to organize the configurations per-vendor, or to
separate the minimal configs from the demo ones, or something.

Or we could move the configs next to the board/ related files they
correspond. Hm, wait, that's what we used to do 5+ years ago :-)
