I thought it might fall into the non-split ortholinear category, but that makes sense once you pointed it out.

It only fulfills point 4 I think, but it does look like it might not be in line with the rules on the sidebar, so it will probably get removed (admittedly I don’t know if posts need to be manually approved here, so I’m not sure about this).

It might not be “hand-shaped”, but the use of layers (and tap-dance/home-row mods) will minimize hand-movement, which is another way to approach ergonomics.
