Analysis

1. The PR only adds proxy_id to browser response types but lacks specific tests targeting this new field, which could lead to undetected bugs in how the field is populated or handled.

2. While the change is additive, there's no clear validation provided for the proxy_id field format or constraints, potentially allowing invalid data to be passed through.

3. Documentation exists but may not fully explain the purpose and usage context of proxy_id to new developers, creating potential maintenance challenges.
