It's a tradeoff, isn't it? We don't know how the user ended up with this
config, what they were trying to do, nor how common it is. Clearly the
config makes no sense and is broken, but by alerting the user, we are:
- maybe doing some good, because now they know that whatever they were
trying to do didn't work, and can clean up the broken config
- maybe doing some bad, because it was not (and is not) hurting
anything to have config that nobody bothers to do anything with. But
if we die, now the user is presented with a situation that they know
nothing about, and must resolve it before continuing with their
unrelated work.
