If you feel that way, that's fine, but yet the real world metrics are what you want to achieve/surpass in this thread, right?
The delineation is done to separate what each ability score does and how it contributes to the whole in each edition. So, when I see someone argue something should be "this ability score instead of that one, or maybe a choice between the two" more often than not it is because they want to be able to accomplish something without having to devote better scores to another ability score.
Such arguments are why our house-rule is weapon damage is adjusted by STR, never DEX, not even for finesse or ranged weapons. Only monks retain the DEX to damage benefit (a perk of the class), and loading weapons don't get any bonus from STR or DEX. For instance, how many times do we have to show why longbow users certainly required a good deal of strength to employ their bows?
At any rate, it is time for sleep. Obviously you play your game and your table your way, and as you already admitted if for no other reason, for Pete's sake don't use DEX for this stuff as well, it is already an uber-stat.
