You didn't mention this bit in the changelog, and I'm not 100% convinced
it was the best idea in the first place.  It's going to result in some
very big timeouts if it goes off, and we really should be doing
validation much earlier in the process.

Not only the ternery operator, but the version without the second
argument for extra clarity!
