Why does Angband sort inventory?

[t4nk]

Start a human warrior. Your inventory looks like this:
a) a Ration of Food
b) a Potion of Berserk Strength
c) a Scroll of Word of Recall
d) a Wooden Torch (5000 turns)

Now, drop the potion. You know what happens; the scroll is quietly moved into slot 'b', and torch into slot 'c':
a) a Ration of Food
b) a Scroll of Word of Recall
c) a Wooden Torch (5000 turns)

But why? What is the purpose of it? As far as I can tell, this is an entirely negative thing, and just promotes the use of such an obscure feature as inscriptions and screws new players (who don't know how to use them). Go observe Dungeon Crawl's players (on online servers), pretty much no one uses inscriptions there, even though Crawl (AFAIK) also supports inscriptions. That's because Dungeon Crawl doesn't shuffle your inventory (you can do it manually, if you want).
Are there some positives that I'm missing? I don't see any.
(note, this is not something that can be changed in the ui, that's a "feature" of the core game, see calc_inventory())
