Sure, but that greatly reduces the launcher's usefulness - especially when
you consider how universal imbedded electronics are becoming. In 20 years
I'd expect anything more complex than a brick to come with some combination
of imbedded sensors, computers and communications gear, all of which is
pretty delicate unless you go well out of your way to harden it.

Mind you, I have some hopes that this will turn out not to be a problem for
the acceleration range we are interested in, but it definitely needs to be
