> Yes! Why is support for PUT and DELETE not specified in HTML specs?
IIRC, it was in an earlier draft of the WHATWG HTML spec, was implemented in a beta version of Firefox, issues were raised with the semantics of the Firefox implementation that ended up becoming issues with the clarity of what browsers were supposed to do with PUT/DELETE forms in the draft HTML spec, and the result was taking PUT/DELETE support out of the spec because of the lack of agreement on what should be specified regarding the use of those methods with forms.
ISTR that this issue has been reopened as a bug with the spec since that time, though I don't know if it is currently open or not.
