It is technically not yet in the standard but it was accepted and will
almost certainly be there in the next version. I was there as a guest at
the meeting when this very question was discussed and that is indeed a
feature gap in DuckDB. But as it is a very new feature in the upcoming
version of the standard that is to be expected.
According the accepted change proposal which was discussed when I was there:
INSERT INTO t (a,b) BY NAME SELECT 37 AS b, 42 AS a;
is effectively the same thing as:
INSERT INTO t (a,b) BY NAME SELECT a, b FROM (SELECT 37 AS b, 42 AS a);
