You still would need exec. It would instead be:
s6-setuidgid <uid:gid> exec <cmd> <args>

If you mean manage services as purely a non-root user (s6-rc commands)
and such, it's possible. You would need to set it up yourself, but
basically it would be running a s6-svscan process as a local user and
then running an s6-rc-init using the directories created by that
s6-svscan process. I don't think doing this would solve your problem
though.

I don't think this is logind related. I would expect the same issue
everywhere. I'm no expert on screen at all so perhaps I am wrong, but I
personally would not think it would work without an actual shell active
and running (i.e. you are logged in).
