Sorry, I don't understand the question. Does the “fall back” mean the
behavior before a patch?

Do you mean always connect to the external server and print a URL for a
log file in addition to path of local log file? I don't think mixing
those in one output is good, because for example you cannot do like:
--8<---------------cut here---------------start------------->8---
diff -u <(guix build --log-file hello) <(guix build --remote-log-file hello)
--8<---------------cut here---------------end--------------->8---
As a better approach in addition to ‘--no-substitutes’, maybe we could
implement ‘--only-substitutes’ (as I remember Nix has it)? Such flag
will return a remote log file and will avoid building packages locally.
