Codespaces user here (I set it up for the teams), for about the last 1.5 years in a large corp setting with teams using it.

My experience with is it has been wonderful for getting started and immediatly becoming productive with very complex systems. Most of those systems have 1 (or very few) experts who need to help everyone else with their setups. When problems arise, and they often do, they've become the bottleneck and Codespaces removes that. Those experts can focus on keeping just that up globally versus locally for each individual.

Outside of that scenario, complex systems, I've experienced it to be overkill. The negatives that come along with using such systems haven't outweight the benefits.
