Of course you are entitled to your opinion, but for me it glosses over the issue instead of fixing it. Another issue with armor is weight when carried and weight when
worn. Although plate armor does weight about 60ish lbs. or so, it was designed to fit
relatively well with the weight dispersed so as not to fatigue the wearer as quickly. As such, when armor is worn, it counts only as half weight for purposes of your encumbrance but is still full value towards your max carry. Now, if you put all the pieces in sacks or strap them together and try carrying plate armor, it definitely
feels heavy compared to wearing it.
Implementing small-sized armor (and weapons even) would not have been too difficult and would be more realistic--but I know that was no where near their goal, so
shrug -- we do it ourselves (if we care to, of course).
Besides, too many people would complain that their halfling with a longsword (possible as long or longer as the PC is tall) should be treated more like a greatsword and require both hands, yet deal only 1d10 damage instead of 2d12.
