It's a PostgreSQL extension, so it's nonstandard, but my
understanding is that it's safe to use and there are no current plans
to make it go away. As long as you understand what you're doing, I
don't know of any problems with using CREATE CONSTRAINT TRIGGER. I've
asked similar questions in the past, so you might want to check the
archives.
