Of course, it's my default setting for SSH (and the host I tried to 
deploy
to). But “guix deploy” don't support it; it's the core of the issue 
here.

I didn't mention those options in the initial bug report because IFAIK 
the
ssh functionality for “guix deploy” is provided by guile-ssh, a wrapper
around libssh which isn't related to OpenSSH in any way. So the 
“Control*”
options doesn't apply here, instead they talk about channels and 
session[0]
which seems to be the terms used in the SSH specification.
