We, containerd, suggest user to use binary plugins or RPC-based plugins. Since go plugin has too many restrictions, I'm not sure that how many users use the go plugin to extend the core function in the production. Based on the fact that we put a lot of effort to make external plugins better, suggest to deprecate go-plugin type plugin in v2.0 and remove it in v2.1 REF: https://github.com/containerd/containerd/pull/556 Signed-off-by: Wei Fu <fuweid89@gmail.com>
