we have the events for table fields as OnAfterValidate or OnBeforeValidate but what if we have certain situations where we have not used the Validate Function for a reason in our previous codes but now we need to perform a universal change that must be applied if a field value is changed then we must have an Event Subscriber like OnAfterModifyFieldValue that can be used to perform such operations without using the on Validate function, as of now when it is not available we have 2 options either we find all the code that has used the field without on validate and place the Validate Function on it or we have to write our same code to all the places where the field value is being assigned. I think personally this will help a lot of developers.
