I don't see how peel_to_type is relevant. As far as get_sha1 is
concerned, the interesting thing is actually calling peel_onion. It does
get the context passed to it in my patch, but I didn't bother marking
that the peel feature was used (because it wasn't relevant to the policy
I wanted to implement in the follow-on patch).
But we could pretty easily mark the use of the peel feature, too.
I'm not sure what you mean about the maintenance track, though. AFAICT,
we don't separately call peel_to_type, but just potentially use it as
part of get_sha1_with_context. Am I missing something?
