Debugfs is nice and so are module parameters, but
 * debugfs doesn't take effect early (e.g., if drivers are locking up
   before user space gets anywhere)
 * module parameters either add a lot to the kernel command line, or
   else take effect late as well (if you build =m and configure in
   /etc/modprobe.d/)

So in the same spirit as these
  CONFIG_PANIC_ON_OOPS (also available via cmdline or modparam)
  CONFIG_INTEL_IOMMU_DEFAULT_ON (also available via cmdline)
add a new Kconfig option.

Module parameters and debugfs can still override.
