plugin_registrar is apparently planned for removal: [https://github.com/rust-lang/rust/issues/29597#issuecomment-405170163]

As far as I am aware, they won't remove plugins until proc macros have fuller support. Last time I checked, proc macros couldn't be reexported from other crates, which made it impossible for the tarpc macro to use proc macros without the user explicitly importing the proc macros. It'd probably look like this:

use tarpc_macros::*;
service! {
    ...
}

I removed plugins in #199. Still need to wait for futures and async/await to stabilize.
