That's really only the case if you are trying to replicate tactical grid based combat in totm rather than handwaiving some details to focus on rekevamt things like intent of positioning/movement & whatnot. There's been at least one or two versions of d&d that recommend usinc candy or snacks to represent a combat & those in it. "How far away is x" when I feel like using the tvbox & gridmap is overkill for something & just use totm might be an absolute number, it might be a range, it might be "what are you thinking of doing?... shooting it with your $weapon? You think you could probably(not) do it but there is the blocks on the walls & trees/tall grass/etc between you too". 5e manages to have just enough tactical grid map stuff to sometimes get in the way of totm (compared to fate or something where range is in zones) while being completely lacking in enough to support meaningful tactical grid based combat.It's more about the need for calculating exact range. Are you within 60 feet is a question I can immediately answer as a GM. Exactly how many feet away are you is a much weirder question to be constantly keeping track of. One's binary, the other is highly variable, and changes every round.
The reason why people point to 3.5 ranged combat is because it was far more elegant & "three or four times your short range" worked great for totm with the players jumping to "ouch, can we sneak our way to one or two?" with those occasional loose not worth the gridmap things and with the grid map. A lot of 5e's changes are just change & simplicity for the sake of change & simplicity without bringing anything new or improved to gameplay.
