I've come across this technique with exactly that sort of special fixing;
what I hadn't realised was that it's also done with standard wallplugs.

Many people of course won't have a small enough masonry drill, as this
size is probably rather small for general use.

For a long time the smallest SDS drill I could find was 5mm (or even
5.5mm) but then ScrewFix suddenly added two ranges which had both 4mm
and 4.5mm ones, ideal for yellow plugs.
