I'm never convinced by how useful this sort of error handling is. There's
nothing we can do about it if it fails, and logging it doesn't make failures
visible enough to bring them to our attention if our assumptions need to be
challenged. I tend to either ignore the error entirely, or CHECK that the call
succeeds.

That said, it's not something I feel strongly about.
