I do 100% agree on this, but... I've never seen any discussion of the importance of ideas that wasn't exclusively referring to initial ideas.
So I don't think there's really any risk of overindexing; people who discuss this from a pure ideation perspective aren't talking about iteration - at least not in a way that's realistic. The op talks about "linear ideation" and "restarting flywheels" as what seems like esoteric metaphors for iteration but they're entirely focused on pre-build/pre-execution ideation.
