Problem with normal editions coming with the trinkets is that the market has rejected it IMO.
When you go out to eat, having a waiter bring you water is nice, but people at McDonald's don't want that cost and would buy another place's burger.
There's a downward pressure on prices - a game costing more with those things might sell less when other games charge less without them.
So, it's selling people what they want - a cheaper version for people who want to spend less and a better one for people who will spend for it. Just like McDonald's offers a $1 value burger and a $4 Angus burger.
But more than that - publishers find other models make more money a lot than 'selling a game' - DLC that used to be free, subscriptions, F2P bonuses, etc.
Players who spend $60 on a new game they play for a year are pretty much at the top of the spending for a game - yet a year of World of Warcraft for a new player costs $180 in monthly subscriptions, plus maybe $50-$100 for the basic game and expansions.
Dragon's Age:Origins cost over $100 if you bought the game, and DLC, when released - even if it's now been on sale all for under $10.
Used to be, here in California, you buy gas, you get someone pumping it and washing your windshield and checking your oil. Wasn't that nice - then the market rewarded stations who old gas for a lower price where you pump.
