No doubts on that being valid, but on the actual usefulness of this
being always enabled.

Hibernate Search doesn't strictly need it as it does with the class
and root-entity-id, and in other cases we have an "opt-in" approach
for fields.
I'd expect that users might not even know that they can write such a
query, as I found it surprising. I also suspect that for most people
it's just a pointless waste of resources so I think it should be an
option.

Even if we decide to keep it, I'd propose to disable norms on this field(s).
