@l1t1 I think it is expected result like Duckdb does.
D select sum(unnest([1,2,3]));
Error: Binder Error: UNNEST not supported here
LINE 1: select sum(unnest([1,2,3]));
^
D select unnest([1,2,3]);
┌──────────────────────────────────┐
│ unnest(main.list_value(1, 2, 3)) │
│ int32 │
├──────────────────────────────────┤
│ 1 │
│ 2 │
│ 3 │
└──────────────────────────────────┘
D select sum(a) from (select unnest([1,2,3]) as a);
┌────────┐
│ sum(a) │
│ int128 │
├────────┤
│ 6 │
└────────┘
unless there is other well-known db that support the first case, I think we can keep it as is now.

Another viable replacement query is
DataFusion CLI v37.0.0
❯ select sum(a) from unnest(generate_series(1,10)) as t(a);
+----------+
| SUM(t.a) |
+----------+
| 55 |
