What problem does this feature solve?

vue.config.js

module.exports = {
  devServer: {
      port: 5200,
      host: '0.0.0.0',
    },
}

terminal print:

  App running at:
  - Local:   http://localhost:5200/

Shouldn't it be displayed like this?

  App running at:
  - Local:   http://0.0.0.0:5200/

In docker, 'localhost' means that it cannot expose the service to the host unless '0.0.0.0' is used.
In other words, when host is '0.0.0.0', the terminal print 'localhost' is incorrect. May the terminal print '0.0.0.0' would be better?

What does the proposed API look like?
