One possible downside of this is something Armadillo ran into once:
electronics that seemed all right after a mild crash, but in fact were
flakey and unreliable later. Cracked traces or solder joints?
Recovering the electronics package sufficiently intact to get the data out
is one thing; treating it gently enough that you can still depend on it
for future flights is a rather more demanding requirement, and a somewhat
ill-defined one too.
