I think the hardcore REST people have their heads a little in the
clouds.  It's not possible to make most browsers use PUT or DELETE,
AFAIK.

The idea is to allow something like "<a href=..." that uses POST
(e.g. via javascript trickery).  One problem with a form is that it
is a block-level element and can be tricky to fit into available
space.

BTW, "idempotent" is not actually enough.  "Safe" is actually the
key phrase in the specification.
