I only got to use the Workspaces feature for an hour before they fixed the waitlist access check but IMO the real value is that it provides a familiar PR-style interface for the whole process that enables fast iterations.

TFA didn't show a screenshot of it but the per file plans and the diffs are side by side on a single screen so you can update the per file plan (adding and removing files as needed) and then "re-roll" the code changes as you go. With the Codespaces feature you can even launch the project and get access to a terminal to run stuff and presumably feed the output back into the plan.

It makes it really easy to spot deficiencies in the code, add comments in the plan, and instantly regenerate the code (well, not instantly, there was a queue when I used it). It was a lot smoother than my experience with Copilot Chat, Aider, and Plandex.
