Should we deprecate this module since importing with `npm:mongodb` is working well with Deno?

`npm:mongodb` pros:
- almost all driver features are working for me
- maintained by mongodb inc
- universal api style for both node and deno

cons:
- uses node's Buffer instead of Uint8Array
- uses node's Stream instead of async iterator and WebStream
- is not as fast as `x/mongo` because uses node compat layer

Start with issue #380 and its 23-comment discussion. Compare the stated trade-offs between npm:mongodb and x/mongo, including API compatibility, performance, and Deno's Node compatibility layer. Done would require a settled decision about whether this module should be deprecated, but the payload does not identify implementation files or tests.
