I see a future in which legit mail servers are simply expected to be configured within a reasonable bound, and act in reasonably nonabusive ways, or else their mail will be rejected. Here, anyway. Unfortunately, the spammers will likely simply beat us to it, so even these checks become less useful.
Yeah, it just means the spammers will need to fake or steal services better. That's why sender checks are probably less useful than content checks.
I dunno - with 50 million (or more) zombies out there? Sender checks are going to be useful for a good long time. As long as we can keep the fixed-netblock spammers in check with DNSBLs like SBL we'll do well.
I use regular SBL too, but spammers have found ways around RBLs, such as zombies that only send a few messages, etc.
