This seems like a simple feature that should be added for multiple marketing needs. Resetting lead scoring is available in other products (marketo, etc.).
The use cases are many and fairly obvious with the main one being able to hard reset the qualification to 0 for re-nurture and re-promotion from Lead to MQL again when indicated by sales teams (i.e. they have reached out and qualified the lead at a point in time and they are not ready to enage). Reducing scoring is not necessarily the answer for this need in every case.
