One would think right? I mean, if the OP had a sound argument, you would think in all this time there would be even a shred of evidence to support their position that this system would lead to major game design imbalances. /shrug
It doesn't have to be a "major game design imbalance" to warrant a change, just an undesirable element for a developer. The developers at Firaxis Games, for example, did not attempt to limit the effectiveness of save-scumming in XCOM EU because it was a "major game design imbalance", they did it because the behavior was counter to the vision they had for their game.
Of course, what is undesirable behavior or what creates an imbalance worth addressing will differ from one developer to the next. All one can do is bring it to the attention of the developers (and then spend umpteen pages dealing with criticism and personal attacks from people who fail to understand that very simple concept).
Something to consider: I just pointed out in a recent bug thread that candles sell for quite a bit of gold, and asked if that was working as intended (as a lot of candles are available for looting in the tutorial).
Should I have brought that to the developers attention in the first place? Going by the flawed logic many have argued here, the answer would appear to be "no", since it is up to each individual to gather those candles from the environment or not, and one person making ~1000 gold in the tutorial does not in any way impact anyone else since this is a single player game.
Someone else might argue that those candles make a visit to the tutorial feel required rather than optional, or cite concern that all that extra gold impacts the difficulty of early gameplay. None of that is all that dissimilar to the option of save-scumming in front of key containers to trivialize the RNG design and obtain better rewards, in the sense that they are both optional, their impact on the game is debatable, this is not an MMO where your method of play has an impact on mind, any fix can be worked around with the editor, blah blah blah excuse excuse excuse.
In the end it doesn't matter. If it looks like it might not belong in the game - raise the issue during the beta and let the developers sort it out. They're the most qualified to determine what belongs in their game or not. Opinions and debates on the impact on gameplay are fine, but arguments from the peanut gallery criticizing that the issue was raised in the first place are just stupid and unhelpful.
