The intention was to have this option enabled by default everywhere,
but unfortunately at least one case was found where it breaks
compatibility of a program using systemd-run --scopes and expecting
variables not to be expanded:
https://sources.debian.org/src/pbuilder/0.231/pbuilder-checkparams/#L400
Example run:
systemd-run --quiet --scope --description=pbuilder_build_xfce4-notes-plugin_1.10.0-1.dsc '--slice=system-pbuilder-build-xfce4\x2dnotes\x2dplugin_1.10.0\x2d1-449932.slice' chroot /var/cache/pbuilder/build/449932 dpkg-query -W '--showformat=${Version}' apt
Restore backward compatibility and make the option disabled by default
when --scope is used, and enabled by default for other types.
In case --expand-environment is not specified and a '$' character is
detected, print a warning to nudge users toward specifying the
parameter as needed. In the future we can then flip the default.
