Of course, the entire reason this didn't happen years ago is that we
couldn't agree on what keyword to use... you sure you want to reopen
that discussion?
I don't think changing UPDATE is a good idea. It's consistent with
SELECT and people are used to it.
You could argue that something like
DELETE FROM target [ { USING | FROM } othertables ] ...
is the best compromise. Those who like consistency can write FROM,
those who don't like "FROM a FROM b" can write something else.
