I couldn't think of a case for counters where I wouldn't need them
to be initialized at some point. I implemented both cases just in
case someone does want their initialization and usage separate. As
the counter isn't persisted anywhere, hopefully nobody's doing
anything mission-critical with it.

I don't think that's very intuitive, but that's a bit subjective.
It made sense to me to set and return the default value when the key

The current protocol doc says that underflow is detected, but
overflow isn't. I assume that means it'd wrap. We could also define
it to fault or jump to the (specified) default again.
