On: Boeing 787 Suffers Rare Dual Engine Failure on Landing

[zepearl]

Summarized, I understand that you mean that a malfunction in the "reverse-thrust-detector" (which switches off automatically the involved engine(s) when the reverse-thrust is not operating within its envelope => referenced as "feature" below) is more desirable than not to have it?

(because if, when having a mulfunction of the detector's "feature" in mid-air the engines switch off you still have some time to fix/override it, but on the other hand when not having it if your reverse-thrust engages you're screwed immediately - and even if the feature fails nearby the ground you're still be slow & low enough for at least some passengers to have some chance to survive)

Correct?

Yes, no engines is bad but thrust reverser in flight is a instant killer.

Apparently it's bad if done at cruise (due to the small margins in thin air) but if done in mid-air it's controllable.
