LXD - success on OpenWRT (privileged containers) - but problems with unprivileged

Is there any progress on LXD on OpenWrt ?

I found this WIP (closed) : https://github.com/openwrt/packages/pull/8466

Is there any solution for application packaging using LXC/LXD on OpenWrt System ?

I found this (old) : GitHub - teknoraver/snap-openwrt: snappy for OpenWrt

May be someone already have done he job, and may share it ?
May be advice can be shared if not…

thanks
