As I note yours...

However, there is a bit of a serious point here too in that
users never ask for data validation (at least mine never do!)
they just expect it. So I still maintain that any test suite
no matter how basic should always cover some tests
for invalid input data.

Even well intentioned users will make mistakes and a program
that crashes on invalid input is not user friendly - even if the
only user is the author!
