We need a starting point of projects. So the deadlines, planned hours and assignments. With clients as the variable we would like the original dates to stay put, then planned dates to be able to adjust according to client feedback.
We're starting to use Baseline Durations to capture that initial plan's timing, but they reset if the project is moved back into planning and made current again. (We do that move to avoid triggering an avalanche of notices for our teammates aka workers).
However, as you detail, an original project snapshot would provide a more robust view of where the project started including staffing and tasks.
