Yes, I agree, and that's what I meant by "explicitly handled". The thing is
that I don't know if that's the best way to go, as it doesn't solve the "is it
actually enabled" and/or "which implementation is used". At least the patch I
sent, although it's totally a hack, let you know if compute_query_id is enabled
or not. I'm fine with implementing it that way, but only if there's a
consensus.
