Done in revision 2021.

Basically yes. In my local tests, if LightDM loads a non-seat0 seat before a seat0 one, it may try to allocate e.g. VT7 for the non-seat0 one --- which will be completely useless with Xorg-server 1.16 --- and VT8 for the seat0 one. It may lead to little crashes that required me to restart lightdm service.

Even with Xorg-server versions older than 1.16, LightDM should not allocate VTs for non-seat0 seats (instead, it should append "-sharevts" to their "xserver-command" values, or set systemd-multi-seat-x as their default "xserver-command" value).
