Novelty is difficult because it is a jungle of unknown unknowns.

When you trip over an unknown unknown you have a sidequest thrust upon you that you must resolve now… and that might not be able to be solved.

Unknown unknowns tend to branch and sprout off of one another into towering trees and jungles of fractal complexity.

Those jungles can absorb every ounce of your attention until the project runs out of runway and dies.

A common cause of death is getting lost in the jungle.

Side quests on top of side quests.

That's one of the reasons to use boring, established, robust solutions wherever you can get away with it.
