Second order Plugins registering other plugins (like WebC) and settings reuse

[mirisuzanne]

Is your feature request related to a problem? Please describe.

I have a plugin that relies on WebC, and registers a number of WebC components. In order for that to be useful, I either have to register the WebC plugin inside my plugin – at which point the use cannot also register WebC components in their config – or I have to document all the imports to be copy/pasted into the user config.

Or I can provide a drill-down: pass your WebC config into my WebC config, and I'll merge them together. But that's a strange option in practice:

  eleventyConfig.addPlugin(someRandomPlugin, {
    webcComponentsNotRelatedToThisPluginAtAll: [
      'content/_includes/**/*.webc',
      'npm:somethingElse/*.webc',
    ],
  });

Describe the solution you'd like

I don't have a specific syntax in mind. I'm not sure if the solution is generic – allowing plugins to merge multiple registrations – or if it's a specific feature of WebC (in which case I might be putting this issue in the wrong place).
