Indeed.
This year, about 30% of my students wrote "= NULL" in a query at least
once. Probably I or a colleague were called to the rescue for help.
So this warning would save me time, which explains why I reviewed the
patch with such enthousiasm:-)
I'm fine with keeping the current behavior as a default.
