I prefer to think of it this way when I'm in the field using a variety of focal lengths at various distances. Estimating magnification is easier for me than subject distance and focal length. YMMV.

And it becomes very easy for fixed focal length user (or zoom user at the end of the ranges) when having a guidelines overlaid. It is already easy to imagine the frame to half of its size, just by splicing the frame vertically and horizontally to two. That is the framing if you would use two times shorter focal length.

And the Olympus "Cross Hair" overlay helps a lot in zoom usage, as you get the magnification guides, the one that resembles this from microscopes:

As with that, especially the macro, landscape, architecture and portraits photography becomes very much easier as you know how much to change camera distance, angle or focal length to get the wanted composition. And it doesn't end up just there, you can use it as well to modify your lighting equipments as you get the guidance via that for the lights angles, modifiers adjustments etc.

Extremely powerful.
