I see your point. Still, isn't there subsystem-level default that all events are disabled by default? If such, then current hi8435 state breaks subsystem-level rules, which is a [userspace-visible] bug. I'm not sure how far should we go in bug compatibility. One crazy idea could be - make default selectable via device tree (with default set to all-enabled to keep bug-compatibility). But perhaps that's over-reaction.
