Incorrect. Sender-ID breaks forwarders just as much as SPF does,
and it requires all forwarders to implement a change which is in
contradiction to RFC 2822 and which de-optimises the delivery of
messages with multiple recipients.

The alternative to changing all fowarders is a forwarder whitelisting
system which eliminates what little security designated sender schemes
alledgedly provide.
