Here you said "knee jerk" where you meant to say "logically principled and wise". Also "common sense" would work in certain circles.

Secure boot isn't a technical solution to a soft/firmware update problem. It's a control mechanism to solve a management problem. Crazy idea, don't put the interface that has access to firmware on the standard interface. Use its own interface and allow motherboard manufacturers to support it for enterprise/datacenter geared systems.
