Yea. The existing trigger argument mechanims is extremely odd implementation wise - they don't have real datatypes and aren't passed via the normal parameter passing mechanism. IIRC we discussed this back when it was introduced and decided against introducing for now. I think the whole trigger argument infrastructure, even for normal triggers, should be rewritten. After that we could think of adding it for event triggers.
