I'm not sure the difference changes the conclusion but I think projects demanded certain workflows and resultant processes, not the other way around. That's why Jetbrains has so many workstream specific IDEs that sold very well. The processes didn't go away but a lot of us changed our IDE surface. Those processes still need to exist, largely, but the way in which we invoke them is moving and changing. To some degree, the processes are also changing because other factors are changing outside of the tooling.

For example, I use Codex and Claude Code by default, but when I need to look at the API surface, read tests, etc I have those tools setup to open Zed. Zed is also rapidly evolving in the other direction, where it's closer to the tools that are opening it. It won't be long, I think, until I can continue my prompt from inside Zed.
