embeddeds without self-link shouldn't be dropped

[beuss]

When an embedded does not contain a self-link, a warning is printed and the item is ignored. While the spec looks contradictory, the embedded should not be ignored
The HAL spec is clear on this point:

The reserved "_links" property is OPTIONAL.

The HAL-FORMS spec looks contradictory since it states:

[the link element] is a RECOMMENDED element

and then (while this looks to break HAL backward compatibility)

Every HAL-FORMS document SHOULD have at least one link element in the collection with a key value set to self
[…]
Clients MAY reject a HAL-FORMS document that does not contain a link element with the key value set to self.

It recommends to defaults self-link to the URI used for the request but this looks incompatible with current cache handling in ketting since URI is used as a cache key

Is there any hope to have this behavior fixed?
