Ludo‘ fixed the issue with the commit 7f20e59a13a6acc3331e04185b8f1ed2538dcd0a.

For posterity, here is the workaround I was using a few month ago and is now
unecessary. The session filed needed to be manually set with a call to
"openssh-ssh-session" from (guix ssh):

--8<---------------cut here---------------start------------->8---
(machine-ssh-configuration
  (host-name "foo")
  (system "x86_64-linux")
  (session (open-ssh-session "foo" #:user "root"))
  (host-key "..."))
--8<---------------cut here---------------end--------------->8---

Currently the following suffice:

--8<---------------cut here---------------start------------->8---
(machine-ssh-configuration
  (host-name "foo")
  (system "x86_64-linux")
  (user "root") 
  (host-key "..."))
--8<---------------cut here---------------end--------------->8---

Cheers,
