Yes, it would. Thanks for the pointer! I missed the "handle_boot_enabled" parameter, too, for some reason. I think this could also be enough for some scenarios. As a result, it seems it makes sense to respin my patch, and test it with "handle_boot_enabled" and the patch series you were pointing out. I'll try to get this done within the next two weeks.
