It's not really as bad as you make out.
Using the Manx register as an example as its where most of the people we sell aircraft to register them. They will automatically give a years implementation period if and when the new regs come into place. So worst case that's two years to go.
They will also publish an outline ops manual.
I'm not sure you're correct about CAMO being mandatory. But even if it is it can be had very reasonably, and if you were on an AOC it is mandatory anyway. Most people have their maintenance managed already anyway. And quotes I've seen from the "big" management companies for CAMO are horrendous. Absolutely outrageous when one considers what's involved.
I've no axe to grind or product to sell. Other than seeing owners enjoy the ownership experience. But I've seen a lot of people very dissappointed by their management companies ripping them off after a hard sell based on "economies of scale". And making profit which is subsidised by said owners aircraft being flown at less than the real cost to the owner.
