- Implement a way to enable triggers to check which columns are affected by the triggering statement.
This can already be done by comparing old and new values, no?
UPDATE foo SET x=x, y=y
is different from
UPDATE foo SET y=y
if triggers maintaining x are involved. I had this case, and had to do quite weird stuff to implement this.

joining column's datatypes do not match
