The reason I didn't make array types for domains is that I have
absolutly no idea how to manage the below case once point 4 is
implemented.
create domain dom as int4 check (VALUE > 5);
create table tab (col1 dom[2][3]);

Not entirely sure, except the book I had (SQL99 Complete, Really)
specifically forbids it.

Yes, I'm slow and only capable of one step at a time. Foreign key
constraints are the other real point.
