The problem is that the primary purpose depends on the context.
In some cases we just want to know if a mapping exist, but don't want to
actually trigger a mapping, in others we want to trigger a new mapping,
but that will happen only if the backend supports it.

So this is just a sort of preference. The need to specify query_only is
really only a hint we use to avoid mapping unnecessarily, but 99% of the
time we see a SID or a UID/GID we really want to make sure we have a
mapping if possible.
