I would suggest that a less "invasive" approach, more compatible with the
traditional sysctl, would be to have systemd-networkd default to _not_
configuring per interface forwarding, and then to _dis_able per interface
forwarding by specifying "IPForward=no" in the .network files, when desired.
<span class="quote">> this was an underdocumented change in 219</span >
For the future, a bit of warning can help avoid "breakage" and unnecessary
work.</pre>
