If leading WhatsApp Calls, would you implement group calls with more participants or focus on call quality?

Introduction

The trade-off we're examining today is whether to implement group calls with more participants or focus on call quality for WhatsApp Calls. This scenario touches on the core functionality of WhatsApp's voice calling feature, balancing user demand for larger group conversations against the need for consistent, high-quality audio experiences. I'll approach this analysis by first clarifying key aspects of the situation, then diving into a comprehensive evaluation of both options, their potential impacts, and a data-driven decision framework.
