I do think it will have some local value after Android 8 which should start shipping in a few days though. I'll look into having the kernel stash some entropy in pstore soon since that seems like it could be a great improvement. I'm not sure how often / where it should hook into for regularly refreshing it though. Doing it only on powering down isn't ideal.
