Technical Meaning
The WARNING_IPSEC_MM_POLICY_PRUNED error indicates that a Main Mode policy was successfully added to the IPsec configuration, but some of the requested security proposals or offers were not supported by the system.

Error Details
- Error Name: WARNING_IPSEC_MM_POLICY_PRUNED
- Numeric Code: 13024 (0x32E0)
- Short Description: The Main Mode policy was successfully added, but some of the requested offers are not supported.
This error is specific to the IPsec configuration process and relates to the Main Mode phase of establishing a secure connection.

Developer Interpretation
Developers should interpret this error as an indication that some of the requested security features were not supported by the system during the Main Mode phase. This could be due to limitations in the IPsec stack, hardware constraints, or other factors. The policy addition was successful, but certain components may need to be adjusted or reconfigured.
