I feel like our use case at Grapl wasn't particularly crazy. It was just slightly more than "I'm a dev building a library and publishing it" - we had a workspace with multiple devs and CI/CD. CI/CD was really slow - issues with caching, rerunning unnecessary tests, etc.

Plus we had some Python code so unifying our builds would have been ncie.
