Huh? The only "current behavior" with other operators is failure:
regression=# select (1,1) <* (1,2);
ERROR: operator <* is not supported for row expressions
In any case, you can get the equivalent of the current behavior by
writing out
1 <* 1 AND 1 <* 2
so I don't see any strong need to support non-SQL-spec behaviors here.
