It'd be best on an X list, but I've not found one with enough
signal-to-noise or enough baseline signal.

No, that is precisely the behavior I do not want.
-ac disables host-based access control mechanisms.
Enables access by any host, and permits any host
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
to modify the access control list. Use with

running test suites remotely.
Xserver(1) and Xsecurity(1) talk about how to use xauth over xhost,
but not how to lock out use of xhost.
