Hello Pierre,

> series, see 
> https://lists.gnu.org/archive/html/guix-patches/2020-07/msg00965.html
>
> In the meantime though, we can update the 10.x series still, it's in
> maintenance mode, but still supported until April 2021 [0].

Thanks for explaining the context. This LGTM, feel free to proceed :).
