Think about it for a minute. You have varchar2 limited to 4000 bytes. Then you have text to cover 4K to 2G range. Then you have to rely on some other option to be able store data bigger than 2G (split it into chunks in your application????).

If you suggested such a design to programmic language community, you would be laughed at. Of course, you have a performance disclamer to back you up, while in reality there is nothing that makes text datatype inherently less performant than varchar2. In fact, those ugly length limited datatypes are just artifacts of the early SQL days, when Fortran was the most popular programming language, and datatypes with dynamic memory managenent were yet to become mainstream.
