_spikeExtension does not work with pug-static-loader

[NikitaVlaznev]

Having index.pug in views and this in app.js:

module: {
  rules: [{
    test: /\.pug$/,
    use: [{
      loader: 'pug-static-loader',
      options: {
        _spikeExtension: 'html',
        pretty: false,
        locals: { foo: 'bar' }
      }
    }]
  }]
}

leads to getting index.pug in the public folder.

Need more info here -- is the file compiling, but its just the extension thats not working? Or is it not compiling at all?
