This particular issue of substitute URLs is fixed in fb4bf72.

The more general problem remains though: for all the other options, like
max-build-jobs, timeout, etc., the client settings take precedence over
the daemon settings because the =E2=80=98set-build-options=E2=80=99 RPC doe=
sn=E2=80=99t provide
a way to say =E2=80=9Cuse default value.=E2=80=9D

The fix for that will be either: (1) a =E2=80=98set-build-options2=E2=80=99=
 RPC that has
a way to leave some settings unchanged, or (2) a =E2=80=98get-build-options=
=E2=80=99 RPC.

Option (1) is simpler and more efficient, but option (2) could be
interesting.
