I have certainly seen a much longer lag between a phone release that is not a Pixel and it being rootable+able to run Lineage compared to the Cyanogen days.

I've also noticed that nowdays, few phones are able to run more than one newer major Android version ahead because the OEM will simply not release the firmware needed to run newer versions and Lineage doesn't have the capacity to update/release their own firmware rebased against the latest Android, (I am talking about things such as the radio firmware, OnePlus is a famous example I know of).
