Yes yes, i know. About 1 year ago we both look this all up.. 
The sddl is fine, and works better if you set ignore systemacls. 
Because then you can have O:DAG:DAD:  its only not shown on the system.. 

This imo also the interesting part and still i dont agree,.. Because 
I have do gid's on "domain users/guest/admins" on my AD backend DC's and members. 
0 problems here. 

getent group "domain users"
domain users:x:10000:.... Here all my users with uid. 

getent group "domain admins"
domain admins:x:10001:admin,administrator

getent group "domain guests"
domain guests:x:10002:guest

domain computers:x:10006:
Yes. Here no computer in the group, but gid was added, this works fine. 

Test it Rowland and you will see it works, maybe i found some great loopholes here.. 
But i really like the ignore systemacl because if fixes a lot of SID/UID/GID related problems. 
I also advice to use it the least as possible, but imo, sysvol netlogin profiles users and a deploy share
really bennefit from the parameter. 
This work really good for me, as of samba 4.4+ now at 4.7.4.
