Problem is, with traditional cranks and chainline this produces a massive kick into the pedals on big hits, and worst case can pull chains apart unless you put a secondary freewheel in the crank, or switch to a high idler pulley like this that’s concentric with the upper pivot. This design seems to additionally move the derailleur inside the chain stay for protection, which makes sense for hardcore MTBs. Pinkbike is basically a hardcore MTB site at this point…
Another more conventional high pivot design that’s getting a lot of good MTB press:

Plenty more examples in the MTB world if you cared to search for ‘high idler pulley’
nothing to do with touring unless your tours involve 60 foot hucks and a Red Bull helicopter hovering overhead and filming you
absolutely. I've never even ridden a dual suspension bike, let alone having any amount of offroad talent to take advantage of hammering over stuff at speeds that make my eyes water watching vids of guys and gals with mucho talent and mucho cajones/bravery/nuttiness just fly through stuff that would have me stopping and walking down.
and yes, specific frames and etc all make this a neat idea, but would it be able take over any of the specific market? Probably not.
