It isn't really a ratchet (so some of the rest of your reply is moot). It
is a way to publish a single long term public key that people can encrypt a
message to, but with the ability for you to delete part of your secret key
to prevent a later leak of your key from compromising past messages.

It is a way to achieve the same forward security as 3DH, but without
needing both parties online at the same time (and avoiding signed
ephemerals).

Or at least that is my interpretation.
