Thanks for posting your experience, Nik. You made the transition into a manager-free system very successfully; I wonder if that is true for everyone. Some of the aspects of a hierarchical system give people ways to hide and props to lean on, which may be hard to give up. You have relished the responsibility for getting the work done and it sounds like you are thriving. Do you know if the organisational system is based on a specific model, such as holacracy?
It would be good to think that more organisations can follow this 'trend', although it will be harder for existing organisations to transform than it is for new organisations to structure this way from the beginning.
