Not that it helps you much, but there’s an open bug on this topic:
<https://bugs.gnu.org/25569>.

I agree.

A quick workaround would be to do something along these lines:

  # herd stop guix-daemon
  # http_proxy=… guix-daemon --build-users-group=guixbuild
  # guix system reconfigure config.scm

where config.scm has the relevant proxy configuration of in
‘guix-configuration’.

Would that work for you?

HTH,
