It saves a bit of time, but doesn't seem to make a difference on time to market of features, products, improvements or bug fixes.

In my experience, it's a quality of life improvement, but the things that dictate actual time to market is bottlenecked by things that aren't solved by copilot, such as overall design, decision making, requirements gathering, code structure/architecture, solution ideation, user acceptance, infrastructure setup, etc.

I think if it eventually could help with those other tasks, you'd see time to market gains, and that would start to make it really valuable.
