Yes. Currently, we have three functions with `supportPartial=false`:
`hive_udaf`, `collect`, and window functions. The former two functions cannot
support this because we do not have byte-backed mutable and growable
`ArrayData` and `MapData`. I think, if we implement these data structures, we
can set `true` at `supportPartial`. However, window functions need ordered
evaluation. So, since the name is kinda misleading, I think.
