As it turns out, this PR is introducing the very ambiguity that DRILL-5830
tried to remove from DRILL-5546. That is, we now have to separate ways to
expand the wildcard: this way and the project push down way. We need this
commit, so we'll accept this for now. But, moving forward, we should clear up
this ambiguity.
