| For all other topologies, the server address on which the operation failed MUST be provided to the server selection | ||
| mechanism as a member of the deprioritized server address list only if the error is labelled with | ||
| `SystemOverloadedError`. All other retryable errors MUST NOT cause the server address to be added to the deprioritized | ||
| server address list. |

There was a problem hiding this comment.
Could you add a brief rationale or Q&A section to explain this decision? IIUC it's so we don't change the behavior of retryable reads for non-overload errors because that might have unintended consequences for some operations (eg primaryPreferred reads).
