I think this is folly.  It's a chicken game, with four states:

1B - forwarders use SRS, recipients enforce SPF
2A - forwarders operate traditionally, recipients do not enforce SPF
2B - forwarders operate traditionally, recipients enforce SPF

3 - forwarders use their own address in the RFC2821 Mail From.

That's in effect sender rewriting, of which SRS is just a specific 
implementation.  So it's basically the same as 1 in the above.
