Because read only transaction usually don't consume an xid. So yes

Thank you, so what would be the official way to monitor txid consumption (from a MVCC / Freezing admin POV)?
I'm not sure what you're really looking for.
I've been as explicit as it gets. When ppl talk about vacuum freeze what they have in mind is xmin's and xmax's and the rate that xids grow and consume the 2^31 address space, so I find it strange
that such a basic metric is not included in the core statistics collector.
That's all.
