In general it is good.

I have two questions:

Shouldn't it be an hard error when client sends old metadata? I do not like
the warning because when you receive a warning it is too late to cancel the

2) Client/server side plugins.
I expect that some very special features (like client-side OTP provisioning)
might depend particular version/range of version on the client.

Will the metadata include version range which can be checked on client side to
make sure that everything is compatible (for given command/plugin)?

Other than that it seems reasonable. I'm looking forward to see more details!
