We might want to quote an authoritative resource on that, perhaps in
the footnote?

This combination of version+commit is something I'd generally
discourage (my reasoning for doing so already explained elsewhere), so
to me it might make sense to still explicitly point attention to it. 
Perhaps setting a package-property such as (upstream . contentdb),
which would also make it clear why we don't e.g. want the latest-git
updater to apply?


Otherwise LGTM.
