The basic pattern here makes sense but rather than doing this
specifically in the case where we have a bypassed supply we didn't
resolve yet I think we should instead always try to resolve the supply
but ignore the error unless we actively need the supply. I'd be
surprised if we didn't run into other cases where we need to do this so
it seems better to try the resolution in one place.
