Fortunately it can be fixed, and it's safer to clearly specify things.
The prints are there because when the description is wrong enough to
cause things to blow up we can fail to boot or run messily and
forgetting to describe some supplies (or typoing so they haven't done
that) and people were having a hard time figuring out what might've
happened.

It'd certainly be good to name anything that doesn't correspond to one
of the existing semantics for the API (!) something different rather
than adding yet another potentially overloaded meaning.
