DRIVERS-1448 says:

Note: Combining Limit and Batch Size for the Wire Protocol in the CRUD spec can also be removed as part of this ticket.

We should make that change. Also we need to find a spec to mention this change somewhere, likely the crud spec and find_getmore_killcursors_commands.md.

Any updates on this PR? Node received a user PR today that fixes a small bug in our client-side limit tracking. It would be nice to remove the logic altogether.

I am busy with other project, so I am afraid I won't have bandwidth to maintain this. I am gonna close this PR and feel free to take over.
