I am probably late making the comment, but you
probably stand a significant chance of having a bug
crop up during development that will eventually be
traced back to NOT having done something like spec'ing
for wider limits in temp, noise tolerance and/or power
supply issues.  If this happens, the time spent
debugging in the testing the design phase will likely
exceed the time (and effort) required to just spec out
parts to handle much larger environmental limits than
the basic "standard" you're using to get the thing off
the ground.

Of course, you might NOT run into a problem, and in
that case, you'd end up spending only a little more
time and effort to up-rate the design after basic
development.  But to me, it doesn't seem like the
initial effort would do anything but potentially speed
up development, and could potentially save you some
serious headaches...
