I don't see how this could possibly be. Ease of development could mean the difference between your next favorite game existing at all. Or having the funds to become your next favorite game instead of cutting scope into a mediocre game that never got to realize its full creative ambition.

Anything that helps people create AAA-quality games without needing the coffers of Electronic Arts is good for gamers.
Do you have any examples of the complexity of AAA graphics caused a game to either have its scope cut, or not exist at all? The only one remotely close to that is Destiny 1's devtools making created/editing levels difficult. However, that game had more fundamental problems, like needing to support the PS3 in addition to the PS4.
