OK, that should have read that Microsoft do not support (maybe provide is a better word) a free Exchange hybrid License key for Exchange 2019 (unless you can advise me this has changed - I believe this to still be true and can find no evidence otherwise).
Therefore, the majority of hybrid deployments end up being Exchange 2016 (which does come with a free hybrid licence key with O365 Enterprise plans) as opposed to Exchange 2019. This is an easy decision for most as no one really wants to pay for a licence for Exchange 2019 for a server they don't actually want, but Microsoft tells them they need to have to remain supported after their migration.
In short, I phrased my post badly though. Apologies.
