Why are we discussing this topic again at all? Again?

Even with consumer software, you may want to crash immediately so 
that you actually get complaints from testers/buyers instead of 
having a silent, invisible bug that no one will report ever.

Actually leaving checks is imho perfectly valid for consumer 
software, if you don't do that the next consumers will have the 
issues that didn't get reported.
