Fix #14532. As discussed on the call today: 1. We'll stick with `format = "base16"` and `hash = "<hash>"`, not do `base16 = "<hash>"`, in order to be forward compatible with supporting more versioning formats. The motivation we discussed for someday *possibly* doing this is making it easier to write very slap-dash lang2nix tools that create (not consume) derivations with dynamic derivations. 2. We will remove support for non-base16 (and make that the default, not base64) in `Hash`, so this is strictly forward contingency, *not* yet something we support. (And also not something we have concrete plans to start supporting.)
