As a workspace growth, the mono repo tool should provide:

Fast local computation caching

Fast local task orchestration

Fast-distributed computation caching

Fast-distributed task execution

Fast transparent remote execution

Fast-detecting affected projects/packages

Understandable workspace analysis

Understandable dependency graph visualization
