Neal Richardson commented on ARROW-13498:
-----------------------------------------
Maybe this is my confusion in ARROW-13344? Because the ScanNode takes a filter
and projection, I don't ever create a FilterNode because I assume that the
filter is already applied--why else would I provide a filter to the ScanNode?
But maybe that's mistaken?

> Lots of variations of this fail, both scalar and grouped agg. It's really
> obvious when you filter on the group-by column and then you see those groups
