As I recall these are all plaintext-equivalents; i.e. there is no security benefit from using these pre-hashed values, so they've been deprecated already. The plugins will retrieve and use them if they're present, but nothing creates them.
They are _not_ plaintext equivalents. They are realm-limited, so compromise is limited to just the set of services sharing that realm (in many cases a single service). i.e. they don't let me use your password to log in to gmail, or get a shell on your box.
The fact that the cyrus folks decided to deprecate these in favor of storing actual clear text passwords makes me a sad panda. And demonstrates a lack of understanding of the security issues involved, or a very different cost/benefit analysis than I can imagine.
