I never said the features are useless. I also didn't say you should do everything in userspace. I asked because I wanted to know what exactly are the things you are missing from what is possible today. So, this could maybe be added to the current watchdog frameworks. Adding a new framework (with lots of issues) and requiring a new set of drivers won't cut it.
