So if I understand this correctly, domains which receive
their email through some sort of front runner, like an ETRN
service, want to be able to do SPF checks? The problem
would then be that the front runner would be delivering
messages which would fail SPF because the front runner is
not the originating domain's outbound server?

If a domain has its mail sent out by another domain,
wouldn't the "include" parameter of an SPF record negate
the need for SRS?
For example, if "domaina.com" routes outbound mail to
"isp.com" and has an SPF record of "include:isp.com
-all" would that not pass the SPF test when "isp.com"
attempts to deliver "domaina.com"'s messages assuming
"isp.com" has a valid SPF record?
The problem is that receivers set up forwarders. Not
senders.
There is no way to know in advance if your message will be
forwarded. I supposed if you have one persistent
problematic case, you could solve it this way, but it's
not a general solution.
I think a better solution is that recievers should
whitelist forwarders from SPF checks since the forwarder
is acting as an agent of the reciever.
