I loved the original promise of Dagger and it’s still 90% great.

But one flaw (IMO) that it can’t export artifacts and import into other steps without breaking the cache.

Eg if you provide monorepo as input, and then on some step narrow your build to one specific dir, then even when files change outside of that dir then caching still is invalidated.

Which makes it extremely verbose and maintenance nightmare to keep multiple narrow inputs and keep all those paths up to date.
