Do we need to set externalsPresets when target: 'node'?

[OliverJAsh]

Regarding this part of the docs:

webpack-node-externals/README.md

Lines 32 to 44 in fc08261

	**Note**: For Webpack 5, in addition to `target: 'node'` also include the `externalsPreset` object:
	```js
	// Webpack 5
	const nodeExternals = require('webpack-node-externals');
	...
	module.exports = {
	...
	target: 'node',
	externalsPresets: { node: true }, // in order to ignore built-in modules like path, fs, etc.
	externals: [nodeExternals()], // in order to ignore all modules in node_modules folder
	...
	};

When target: 'node' I suspect the default for externalsPresets will be { node: true }:

Therefore I'm not sure we need to set externalsPresets when target: 'node'?
