AWS documentdb documentation change
Summary
Entire documentation page for the $pop operator has been removed, including all content, examples, and code samples
Security assessment
This change removes documentation for the $pop operator entirely, which could indicate deprecation, removal of the feature, or documentation restructuring. There is no evidence in the diff of security vulnerabilities being addressed - no mention of security issues, vulnerabilities, or security-related changes. The removal of documentation could potentially impact security if users are no longer aware of how to properly use the operator, but there's no direct evidence of security remediation.
