This looks good, but would it be possible to adapt this to work with the
series endpoint [1], rather than the patches one?

1: https://patches.guix-patches.cbaines.net/api/series/?order=-id

I think the use of the patches endpoint currently is just because
previously the Patchwork checks information was used. Now that Patchwork
checks aren't used, I think the series endpoint can be used instead, and
this should map much more closely to the data structures you're trying
to construct.

Thanks,

Chris
