I try to avoid the customize facility as much as I can, because it
doesn't allow to set values based on conditions like the system-type,
for example.  If I do some customization "by hand" in my init file, I
have all the power an flexibility of elisp for doing what I want.
That is not possible using customize.  So currently I use customize
only for face-related settings, and BTW I have to maintain several
custom files (one for GUI sessions, other for the Windows console and
other for the Ubuntu console) because each environment requires a
specific visual customization.

Therefore, I'd like to be able to set `auto-revert-use-notify'
directly in my init file, with `setq', but if that is not possible, I
will have to adapt myself.
