Unfortunately, it is not that simple:
 - we are already forced to use --ignore-dependencies when network
service tried to start/restart some network dependent services (like smb
when ip address or dhcp hostname changes).
 - 2nd stage of our installer is running as part of the boot process and
tries to start some services itself, but trying to start them will
block, before they are already in the queue for being started and
blocked by other services will be started once the installer has
finished its duties. There, I've also discovered the merge of actions in
the queue is not working at 100% : if you specify --ignore-dependencies
on a action which is already in the queue, it will be bumped on top, to
be processed but the options seems to be dropped (causing a deadlock).
But that's another story.

I was planning to handle this environment variable in our tools but
tools team would prefer to have it in systemctl. I guess I'll have to
maintain this patch downstream in openSUSE :(
