complete fullfillment with some quantities lower than commited
In https://github.com/valueflows/valueflows/pull/471#issuecomment-478255415 I suggested something like acceptedCompleteFulfillment for situations where event had different quantities than commitment (especially lower) but agent wants to mark that this factor of commitment still should considered fully fulfilled.
While it seems more relevant when commitments get made on use, it might play less or no role where commitments get made on reserve and for example the whole duration of reservation gets fulfilled even though usage lasted shorter time.
