I would suggest that the mail network is already mangled. This is a way to
clean up my own little corner of the network with no impact to you. You
would be under no obligation to do this for your own network, or to query
my network. You can ignore it, just as you ignore any other scheme you do
not want to participate with.

The silver bullet exists, but in the form of a new message format and
transfer protocol. Goooood luck with that one.

Leathering through RBLs, reverse-path verification, keyword filters,
distributed checksums, are all things that people use now. An authorized
sender RR/owner/whatever is just another tool in the toolbelt. This one at
least has the interesting property that it is voluntary, meaning that when
it exists, it has more credibility than third-party mechanisms.
