Whether the zero device ids go on the wire. One owner for the rule, read by
the Android header layer and by the Pigeon upload. The build-level fact is the
zero-rating table (ZERO_HEADERS): the 429/448 builds carry the ids with the
pair, the 450+ builds carry neither, so the table is the single wire-presence
fact. The device must also have uploaded its attestation key; a fresh install
holds none.
