Ah-hah. I'd noted that that code wasn't being reached when I did some
code coverage checks this morning, but I hadn't found the cause yet.
Yeah, replacing the if-test with an assert seems fine.

Possibly. All that code could stand to be rethought, probably, now that
its mission is just to handle the SRF case. But at least all the cruft is
in one place for the moment. And I don't think it's anything we have to
fix before v10, it's just cosmetic.
