My shareable config uses rules from an external plugin and I would like to make it a dependency so the user doesn't have to manually install the plugin manually. I couldn't find any docs on this, but it doesn't seem to work, so I'll assume it's not currently supported.

module.js:338
    throw err;
          ^

I assume it's because you only try to load the plugin when the config is finished merging.

Other shareable configs that depend on a plugin instructs the users to manually install the plugin too and they have it in peerDependencies. I find this sub-optimal though and I don't want the users to have to care what plugins my config uses internally.

The whole point of shareable configs is to minimize boilerplate and overhead, so this would be a welcome improvement.
