I'm not sure why you need to add UNSPECIFIED here; the point of NONE is
that no format had yet been specified.

It looks like the only difference is that finalize_deferred_config
converts unspecified into NONE. But I think you can just use NONE for
both cases, and drop this hunk:

You lose the assertion that finalize_deferred_config has been called,
but I think the resulting code would be simpler, as it drops this
die("BUG") state entirely. Am I missing something?
