Yes, we should deprecate them first for sure. As to supporting special
hardware -- there are too few entry points for plugins in current criu
code, strictly speaking good plugin architecture will require a way
more of them. I would rather say our current plugins system is rather
a concept or even PoC and since for that long time nobody proposed
any patches for them I'm pretty sure nobody use them.
