Are you sure you want this? How does it reduce runtime dependencies?

globals are generally much easier to polyfill (/existing polyfills already handle them), so this seems counterintuitive.

The vast majority of these are accesses to process.nextTick() or process.env; I still think you'll want queueMicrotask() as a replacement for the former, and the environment I'd consider passing to the MongoClient as an option (with process.env as the default value)

This is one of the intentions of this doc, to remove the dependence on a global process: Design: Remove dependence on runtime specific APIs.

How does it reduce runtime dependencies?

This change itself doesn't, but it allows bundlers to supplant the variable consistently.

The queueMicrotask change will go in first, then I'll update this PR and mark it ready. We will eventually allow a way for users to pass this information to the client, but that is part of the later milestones.
