INSERT INTO row value constructors

This is just an odd question.  Previously RDBMSs (MySQL, SQLite, IIRC) I've used have allowed row value constructors (optional feature F641 in SQL'03) on INSERT statements.  That is:

INSERT INTO mytable
VALUES (0,'hello'),(1,'world');

Is essentially shorthand for:

INSERT INTO mytable VALUES (0,'hello');
INSERT INTO mytable VALUES (1,'world');

Under PostgreSQL, though, the parser thinks the row value constructors are arrays.  This isn't a problem, per se, except to make me realize that PostgreSQL is unlikely to adopt F641.

Is that correct, or is this behavior expected to change?

This is just a curiosity question.  I expect that PostgreSQL would behave in a similar manner performance wise inside a transaction.  It just struck me as odd when it didn't work.
