But is it useful enough to justify exposing it, documenting it, explaining to users they shouldn't touch it, etc.? IOW do you use it often enough that it's painful for you to have to modify the source and rebuild to disable it?
No, it's as easy for me to just add 'return NULL;' in the file and do a 'make install' in the x11drv directory.
I will check the sample config file to see if it needs to be patched to remove this option there.
