Use Case

As a developer
I want to remove the wire version check from needsRetryableWriteLabel
So that I get accurate retryability checks.

User Experience

• Retryability in load balanced mode can potentially use the wrong check since passing a topology or server to the check reports a wire version of 0 in the descriptions.

  Dependencies

• Removal of support for 4.2 (April 2026)

Risks/Unknowns

• None

Acceptance Criteria

Implementation Requirements
