Hi all,
thanks for the fixes in Eoan. Unfortunately we have a product based on disco and cannot move forward at this time. Being a networking shop, this issue has a serious effect on us and we would like to avoid moving to something like ifupdown2 within our stable branch.
For our users the real impact of the bug is not that that the interface that we are currently reconfiguring is suffering a downtime, but the fact that _all_ interfaces have their aliases removed if networkd is restarted. The proposed KeepConfiguration solution kind of beats the purpose of reconfiguring the interfaces, as old addresses are kept and need to be handled manually. Also it interferes with how DHCP works. I believe this might be an issue for others as well.
From our point of view the ideal solution would be a combination of the keepalived patch that detects VIP removal and systemd version 244 that already supports "networkctl reconfigure" and "networkctl reload".
Is there any chance that v244 is backported to bionic? It is already included in focal and debian stable backports, but unfortunately I am not familiar enough with systemd development to tell what the impact of this would be.
As for keepalived, in bug #1819074 there was an ongoing investigation on the patch, that implements the keepalived transition on removing the VIP. We have traced back this functionality to this patch:

It was born before v1.3.6 was released, so we hope that it is self-contained enough for a backport if v2.0 of keepalived is not included in bionic-backports.
Best,
Balint
