Ahh, cool. I didn't realize dim grew up!

Sure thing. Signing commits allows Dave to use --verify-signatures
when pulling. If something is not signed, we'll know it was either not
applied with dim, or was altered on fdo (both warrant investigation).
I suspect no one else is doing this since most trees are single
maintainer, and it's not possible to sign commits via git send-email.
Since we have the committer model, and a bunch of people with access
to fdo and the tree, I think it's important to add this. Especially
since we can do it in dim without overhead.

Yep, sounds good.

Why would it be desirable to *not* sign tags?
