IMHO the description is clear, but it is not implemented because it doesn't 
give feedback to the user, thus it wouldn't be used.

Suppose a website returns 205 after successful form submissions. If 
user-agents implement 205 as specified in section 10.2.6 (i.e. "SHOULD reset 
the document view"), the human users will find that after clicking the submit 
button, the form is suddenly blanked, and they may think their submission 
didn't complete.

This feature is better realized by returning an entity with 200 status, 
containing the same (reseted) form, and a message such as "submission 
successful, please enter more data" (not to mention using AJAX and similar 
approaches).  On the other hand, 205 responses may be useful if the server 
will interact with purpose-specific clients, because these clients may 
implement the user notification by their own.

BTW, I found interesting that HTTP cares about presentation issues...
