I'd not heard of any of those until just now. So, I did a bit of Googling and from what I can see, it appears that these builders are highly talented types who are more or less ignoring the traditional in favor of using hardware and designs that not only make mechanical/electrical sense, but are practical and highly attractive as well. In other words, no beer can tuners, no six-hole or Eiffel tower trems, no noisy pickups, no knobs with pointless numbers, no controls with 37 functions apiece, no body styles that look like the spastic contortions of some sort of schizoid, real frets that let you get a grip on the strings, etc.
In other words, they're using the state of the art on pieces of art, as opposed to trying to satisfy the über-conservative who can't move off whatever Leo did 50 years ago or the childish who long to be different for its own sake.
As you know, that's what's nice about Warmoth - you can do much the same thing right out of the box, although their bodies/necks don't go too far off the reservation. But, there's no need to replace crummy tuners, goofy bridges or impractical pickups - you just put the right ones on in the first place. Then, you have a wide variety of bodies and necks that can be built out of some pretty exotic woods that can be professionally finished or left to your own tender ministrations. It's a lotta fun.
