The problem with camera formats (sensor sizes) is that there are so many of them. This makes it hard for people to gauge what sort of lens they get when it has 6-24mm or 40-150mm printed on it. The (incorrectly termed) equivalent focal length allows people to distinguish between ultra-wide, wide, normal, short and long tele lenses by relating a 35mm format focal length with the same angle of view.

Alternatively, the angle of view could be specified directly but even fewer people would be familiar with that.

I expect the 35mm format reference to wane away in a couple of generations.
