Fair point, although remaining in the same position without promotion is usually discouraged and not a real option in the long run. Yes, promotion means more value added, but that can be defined many ways. In tech companies it usually includes having more management and/or other non-technical skills (for technical workers). The value could be more aligned with just having more technical skills. It could even be formally assessed by reviewing code and even test, yet from my experience more technical skills had little impact on promotion chances.
