Observation:
> Hopefully Apple has in mind a solution to this situation that will still enable knowledgeable power users to confirm agreement to a sufficiently scary warning and put their Macs in a state similar to what we have today. I worry. What alleviates my worst fears is the knowledge that every technical user at Apple itself needs to use their Mac as the powerful Unix workstation OS that it is. Some of us need dangerously powerful tools. Most Mac users, however, do not — and don’t realize they’re using a dangerously powerful Unix workstation with a very friendly (literal) face.

What Gruber didn't realize is that Apple gives its engineers special internal tools that can bypass the restrictions we on the outside have to suffer.
I'm sure it's also the case that internal development macOS builds are compiled differently than public release builds. They basically have to be for Apple engineers to modify them during development.
