We can add Ubuntu Single Sing-On support via ehooks but I think it's useless so far as it's intended for gnome-software (Software app) and software-properties (Software & Updates app) and it depends on snapd-glib. (see https://launchpad.net/bugs/1752472)
I also recommend to add USE-flag net-libs/gnome-online-accounts -gnome to not install gnome-base/gnome-control-center.
I think we don't need to maintain it anymore as telepathy support was removed. (see changelog https://launchpad.net/ubuntu/+source/gnome-online-accounts/3.27.3-1)
