      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      In PERF-5334 the server perf team discovered that their pymongo benchmark spends a lot of cpu time in MongoClient._get_topology. It's possible we can optimize this code path.

      For context, _get_topology() needs to ensure the topology state is opened. In the past, pymongo allowed a closed client to be automatically re-opened the next time the it was used. It's possible a lot of the work done in _get_topology can be skipped now that a closed client can never be re-opened.
