This is merged and will be required to be verified, however, testing this functionality is... Not straightforward. I'll need to think about how this can be done.
Tested and verified in 4.4.0-0.nightly-2020-04-15-152338 During an upgrade from v4.4 to v4.5, when the machine is rebooted I don't see anything in node journal logs around "no default network" after reboot
