Yes, we considered those but decided to make the check restrictive at
least to start with. We can loosen it up if needed.
The idea was that if validating a numeric entry from a customer, 1. is
almost certainly missing something, +1 is not likely intentional, and .1
we were on the fence about -- some cases it might be intentional, other
times a mistake.
