A better way is to create a public method or function module for the checks. Then you can centralize it, validate or clear import parameter values, set defaults and extend it / change the symantic / create alternate objects, etc.
-> you comment the field as obsolete and any values sent to it are converted to <DUMMY> checks.
This is however more important for adding dimentions to auth checks than removing individual fields or values from individual objects.
