Going off the last priority list, it’s likely there’s still work being done. (It was updated on 9/24/2019 so it’s not terribly old).
I think people got used to the early days when patches came out rapid fire, even for just small things. Since about the end of 2018, they started slowing the patch cadence down by packaging more together.
What we could use is a new, updated priority list for 2020. With the completed items and commentary like the last list had.
