I was thinking about failglob also, but it is not that useful like it looks.

for name in *; do ...; done

In the current state, if there isn't any file, the name variable will 
contain *.
With nullglob name will be empty and script continues after the for loop.
With failglob it will print error message. I think it is not useful.

But you are right, it will cause many breakages (even surprising).
