The benefit is *diagnosis* of certain types of errors that
otherwise produce very mysterious symptoms.
Unit tests would tell me that *something* was wrong, but
not what it is or where it is.

I don't see any difference in ignorability. Just like ABCs, you
can ignore it if you don't use it in your own code. You have to
understand it in order to deal with someone else's code that
uses it, but the same is true of ABCs or anything else.
