Clarification on Using Delete Assignment functionality

I wanted to understand how we should approach the use of the “Delete Assignment” functionality in this scenario.

Specifically, if an employee has a single work relationship with multiple assignments (for example, 2–3 assignments), and we need to completely remove one of the additional assignments (say, assignment 3) from the system, is it appropriate to use the delete functionality to permanently remove it? The assignment can be completely removed from the system and will no longer be visible on the front end. After deleting Assignment 3, the system continues to follow the same numbering sequence, as the next assignment created is again assigned the same previous assignment number (i.e., -3).
