Would it obscure errors? Yes. Is that bad? I'm not certain, but I cannot
think of any cases where it would cause a problem.
Basically it just provides a set of plausible fallback methods. I expect
that a missing plugin would make this obvious for other reasons, but I did
not check to see what actually happens in that case.
If we are not sure, then some unit tests might be in order.
