"None pass scrutiny" based on what measurable criteria? Let me give you one and PLEASE tell me why this reason does not pass scrutiny:
Enterprise customers (who buy Macs in the 100s/1000s) have a program called Automated Device Enrollment that ensure computers they deploy are under management. ADE requires the computer to have a fresh O/S to work. So, when companies started receiving their first M1 Macs, they needed to test their deployment processes and make sure they work. That means multiple test runs, especially if anything failed. So, the IT team would need to restore the O/S between each test run. How do you do that if Apple does not provide a solution?
(And, let me stop you if you answer is Enterprises should not be buying M1 Macs until they are ready. Apple does not necessarily give customers that options. When Apple replaces a model line, they happily replace any outstanding orders with the upgraded model. As a result, many enterprise customers found themselves with M1 MacBooks Air regardless if they were ready or not. While that is great for Apple, it is not always the best situation for the customers.)
