Since we have experimental features (see https://github.com/search?q=repo%3Amongodb%2Fnode-mongodb-native+experimental+language%3ATypeScript&type=code&l=TypeScript) it would be worth centralizing documentation on these.

This could also be an opportunity to maintain a changelog of when features are promoted from experimental status (and in what version of the driver).

For example, CSOT (NODE-6491) and Explicit Resource Management (NODE-6994) could be highlighted initially.
