How should InterSystems balance adding new features to IRIS data platform versus maintaining backward compatibility for existing customers?

Introduction

Balancing the addition of new features to the IRIS data platform with maintaining backward compatibility for existing customers is a critical trade-off that InterSystems faces. This scenario involves weighing innovation against stability, customer acquisition versus retention, and short-term gains versus long-term sustainability. I'll analyze this trade-off by examining the product context, stakeholder impacts, potential outcomes, and provide a data-driven recommendation.
