There is also another layer: when SIPS was introduced, there were tons of articles and videos teaching people to turn it off when they shouldn’t. This ranged from uninformed social media “developers” who confidently spewed dangerous bad advice, to outright bad actors trying to compromise your machine. Non-savvy users could still break their own systems by disabling these features easily.

But largely I agree with you. I wish Apple had taken longer to fully develop a robust solution from the ground up instead of the status quo of piling on year after year to a semi-broken system.
