Not in the tech field but in the consulting space, both Crisp https://dna.crisp.se and Enspiral https://enspiral.com came up with interesting organisational structures that they've extensively documented.
edit: I hope it's clear I'm not trying to diminish the efforts, to the contrary!
Here's also an interview with Richard Bartlett on the matter:

And an episode from the General Intellect Unit podcast relating to this:
That field is also, in my humble experience, in a bind. Very few people outside of the coach/consulting sphere seem to talk about this as fervently as they do. I think mass adoption will require the concepts to be attractive and simple to people who may not be ardent supporters of the cause quite yet.
There's also a whole contingent of people who have built orgs that already do this, they just don't advertise themselves and do their work.
I think the next step is to deeply integrate the concepts of Enspiral and such into organisational design tools. Something like murmur.com but with a super low conceptual barrier to entry, that makes it obvious what the next distributed leadership shift is for a given group. That's what I'm developing, if you're curious contact me :)
People from many different organisations are attending, this stuff is definitely spreading.
