The (object-assign) Babel 5 plugin is being run with Babel 6

Question

After updating project dependencies I started seeing this error, there appears to be a versioning problem with the object-assign Babel 5 plugin.

After the update I use Babel 6, the closest plugin I could find is es6-object-assign, but the use of it results in error (error shown below).

Use of browserify + babelify + object-assign in my app:

var babelify = require('babelify');
var browserify = require('browserify-middleware');
var keystone = require('keystone');

var importRoutes = keystone.importer(__dirname);

// Setup Route Bindings
exports = module.exports = function(app) {
    app.use('/js', browserify('./client/scripts', {
        transform: [babelify.configure({
            plugins: ['object-assign']
        })]
    }));
    // Views
    app.use(function(req, res) {
        res.render('index');
    });
};

Error, when changing to plugins: ['es6-object-assign'], probably because babelify requires the original object-assign package in node_modules/babelify/index.js on line var assign = require("object-assign");:

The `index.js` in `babelify` defines assign as `var assign = require("object-assign");` instead of `Object.assign(a, b);`. `babel-plugin-transform-object-assign` does not detect this pattern and does not replace anything. (as explained here https://github.com/babel/babel/tree/master/packages/babel-plugin-transform-object-assign#caveats) — Peter G., Jan 03 '17 at 13:28

The (object-assign) Babel 5 plugin is being run with Babel 6
