Vessbot, it's not that simple. 25.1309 requires a safety assessment - I can't speak for Airbus, but Boeing (at the FAA's insistence) treats above idle thrust in an uncommanded direction to be potentially catastrophic. That in turn means the probability of the failure needs to be less than 1/billion flight hours (among other things - that also means it can't happen due to a single failure - it needs to require multiple failures).
Somehow I don't think Uplinker is that unlucky...
