No FUD at all. You are just relying on some recipients not enforcing
your -all.
We have a lot of students forwarding their emails to external mailboxes
(usually freemailers even though they have more options here).
I can show you all kinds of examples where the forwarding is rejected in
those cases because the new "sending IPs" are from our machines, not the
ones listed in the From's SPF record.
And no, I don't do SRS, because I don't want to do workarounds to
support a protocol that was broken by design in the first place.
It's your decision (-all) that you don't want these mails delivered to
the recipients, so I don't really care.

Yes FUD, SPF is acting a designed.
If its forwarded, it should reflect SPF record of the forwarding server,
not the from domain, thats the problem of the forwarding configuration.
