It seems like an exhaustingly complex set of boundaries to keep and tends to create winners and losers out of third parties if the boundaries are rigidly followed in most cases. I think being that secure is somewhat admirable, but it also seems like a devastating fall to make if things don’t work out. Different folks have different ways of doing things, I think it’s fine, just not for me personally and I definitely wouldn’t want to be the 3rd party to it either.
