I understand this justification, although I personally prefer "id", but

I don't understand this justification. Are you saying that a table 
frequently has more than one primary key? Or are you saying that you 
prefer foreign keys to be of the format $x_id?

If the latter, unless I misunderstood, that was never under debate--I 
think everyone prefers $x_id for foreign keys. The argument is between:

(Table "foo" with two foreign key columns)

I agree; in actual code you can have it always prefix the table name when 
calling getID() or the like. This isn't really an issue IMO.
