Do you have any plans to make the cache more persistent? In case of no rebuilds, i think we are just loosing cache possibility this way.

Yeah I will make future improvements to only invalidate based on what files are changed. However, that requires some complexity to communicate between the process. The first step is #6156, and I will experiment with solutions in later PRs as improvements.
