Half the point with probe deferral is that it's transparent to anything
that isn't actually resolving a resource - if we have to add custom code
in to everywhere were we need to print an error in a probe path that's
not great either.  We also don't want to silently ignore probe deferral
all the time since then it becomes very hard to diagnose why something
is not instantiating.
