Here is the one I use often (mainly because dummy does not have proper
randr support yet - I have offered to help resolve this..):
https://xpra.org/xorg.conf

Shipping some useful default configs would not be a bad idea IMO.

As for Xorg vs suid, I suspect the distros will want to have control
over the changeover process, something along the lines of:
Xorg -> Xorg.suid
Xorg.suid
Xorg.nosuid
Then, hopefully one day:
Xorg -> Xorg.nosuid
(or just remove Xorg.suid at that point)

+1 for shell scripts that try to do the-right-thing(tm), but from my
experience with xpra there are some tricky arguments to handle, ie:
Xvfb -screen 0 3840x2560x24+32 :10
I don't see how that can be handled with dummy at present...
