That is possible too. But debris build up could happen with a stray
chunk lodging in there somewhere, these mechanisms are pretty
complicated under the hood compared to a saw with out the safety
feature. But like you said it is unlikely for that to happen but if you
are paying a premium for a safety feature redundancy might be an
advantage.

The complexity is in the electronics, however, not the mechanicals.

I'd also posit the SS "brake" isn't redundant; it only works if the
retraction is successful as the blade slamming into the pawl is the
brake--if it don't retract, it don't slam.

Wrong.
The brake is fired into the blade by a spring, regardless of the blade
dropping. It's that action that causes the blade to drop. It tries to
remove some of the inertia.
