Not really. And AFAICT it is still not necessary: what changed is that
an error message will be printed by VALIDATE_DESC() if you do that.
And that is proper I guess? I think it's sloppy code to randomly pass in
NULL to a call and just expect it to bail out, it seems more like
exercising the error path than something you'd normally rely on.
Or am I getting things wrong?
