Why is this desirable? Why is it a good thing that laws only happen after people already die from an avoidable and predictable problem?

I'm sorry I might have chosen my words poorly. I am also advocating more proactive safety crackdown in cases like this.

I'm just relating to the infeasable task of proactively banning permutations of silly designs.

It's not. It's a figment of stupid engineer circle jerk culture where they'll do all sorts of insane actuator and automation implementations to avoid having to design a simple part to withstand the force of a human operating it.

There are many ways to do a fold flush manual handle/lever and hook that up to a traditional door mechanism.
