Configuring the babel loader is not possible when using babelrc file

[stof]

configureBabel currently has 2 arguments:

• a mandatory callback altering the Babel config
• an options argument allowing to configure some settings of the loader rule (excluding node modules or no for instance)

As the callback is incompatible with the usage of an external Babel config, this method throws an error when using it that way. But that means there is no way to configure options in such case.

[stof]

my use case for using an external config file is that babel-eslint requires it

Oh, and of course, my project requires me to include some node modules in what gets processed by Babel (the material-components-web packages which use ES6 syntax in the modules), so I need the configuration of options.

Not related to your issue, but:

an options argument allowing to configure some settings of the loader rule (excluding node modules or no for instance)

Should we deprecate this functionality in favour of #509?

Well, I still like the include_node_modules option talking a list of modules and building the actual rule internally. It would be a shame to loose it.
