The developer is the one who should think about costs. You shouldn't force it on consumers.

> If you are fine with making game development an even riskier financial endeavour than it already is

Yes, I'm absolutely fine with it. We already have a lot of games to play, and if developers have to be very considerate before making something and the number of released games decreases because of this, so be it.
