My stance is that there is no such thing as "pre-concept", it's just different stages of polished concept art.
My concepts looks like this, then I go straight to 3D.
The "concept art" that ends up in the art book that people are familiar with is usually made or polished after the game is finished.
On the topic of "pre-concept art" and GenAI... If you aren't prepared to draw like this and then send to an actual artist to work with, you have no business creatively leading a project. End of story.
