What's the reason that no W3C Forms specifications allows
DELETE as submit method?

   <http://www.w3.org/TR/html4/interact/forms.html#h-17.3 >
   <http://www.w3.org/TR/html4/interact/forms.html#h-17.13.1 >
   <http://www.w3.org/TR/2003/REC-xforms-20031014/slice11.html#submit-options >

In contrast, Web Forms 2.0 allows it:

   <http://whatwg.org/specs/web-forms/current-work/#methodAndEnctypes >

Why do they limit the set of submit methods at all,
given that the set of common HTTP methods can be
expanded?
