I broadly agree with that, but I'm slightly wary about giving people
the idea that parallel-safety will be checked in cases where it really
will not. The stuff that gets tested for parallel-safety is the stuff
actually mentioned in the query. Indirectly-referenced stuff will not
get tested, but if we start marking it that way, then we might create
confusion.
