In some of my builds I need none of the peerDependencies..

I would prefer a error on runtime when I forgot a dependency, like

you are trying to use hot reloading, but vue-hot-reload-api wasn't found. Run:
npm install --save-dev vue-hot-reload-api

or when using a not installed language:

you are trying to use babel but it isn't installed. Run:
npm install --save-dev babel-core babel-runtime babel-preset-es2015 babel-plugin-transform-runtime

Example:

if (style) {
  try {
    require.resolve("vueify-insert-css")
  } catch {
    throw new Error("you are trying to use the style tag, but vueify-insert-css isn't installed. Run:\nnpm install --save-dev vueify-insert-css")
  }
}

I'm willing to create a PR, if wanted.
