If it doesn't work any more, it shouldn't be documented any more.
There are gazillions of more-or-less skilled HOWTO "docs" on the net
that refer to that command. If it should not be used any more

That would be much more easy if one had something non-empty to start
with. Of course I would have stripped down the file to the bare
minimum necessary, but writing that from scratch is just
unneccessarily hard for someone who is not used to writing manual X

I do fully understand that people will use the entire output of X
-configure as their X server configuration, inadvertently turning off
all the magic they might need and causing more support burden that
way, but that can be prevented by, for example, making the generated
file subtly syntactically incorrect or by requiring the user to remove
a certain generated line before the X server will eat the file.

Not having X -configure any more, however, will make writing manual X
configuration to alchemy science as it was fifteen years ago.
