What I can say? Only the "F***king Oracle!" :(

But '' is very good default value. We cannot remove NOT NULL just 
because Oracle treats empty string is null. If we do it, we will allow 
NULL values in many columns and many queries will break. Result of 
comparison is undefined if column has null as value. Thus = and <> will 
be both true for this column. This is even worse!

I suppose DBAL could remove NOT NULL only for Oracle, not for other 
(normal) databases.
