Definitely agree. I've seen all kinds of ways the sides of the tabs have been modified, depending on who or what service did it and in what time period. Many of the modifications were not done very neatly, though.I've used a steel-cutting file, a Dremel carbide grinding bit, a bench grinder. You only need to take enough off so that the front handguard band, once it's glued on, will be permanently relieved from the tab on both sides.
