Well, grommets are probably a requirement as Good Workmanship,
unless you can achieve the same effect some other way.

If the box is mounted on brick, etc, and made good with plaster, there
ain't going to be any possibility of cable movement and therefore chafing.
However, since they only cost a couple of pence when bought by the
hundred, a sensible DIYer would use them as a matter of course.
