What problem are you trying to solve?

Right now you can't use more than 1 plugin that makes use of context. For example, the following test case fails:

test('extending context', withServer, async (t, server) => {
	server.get('/', (req, res) => {
		res.json(req.headers);
	});

	const instance1 = got.extend({
		prefixUrl: server.url,
		responseType: 'json',
		context: { test: true }
	});

	const instance2 = instance1.extend({
		headers: { 'x-test': 'test' },
		context: { something: 'else' }
	});

	const instance3 = instance2.extend({
		hooks: {
			beforeRequest: [
				function injectClientInfo(options) {
					t.is(options.context.test, true)
				}
			]
		}
	});

	await instance3.get('');
});

Right now, context is not merged and not enumerable. This causes the plugin represented by instance2 to remove the context expected by instance1.

Describe the feature

Do a shallow merge on context with "defaults" in /core/index.ts and make it enumerable.

Implementation

I have availability to implement this feature if you decide this is a use-case you would like to support.
