It's interesting if she isn't her Creator's (Astruc) favorite,
Marinette can unironically double as not only a Cautionary tale but also has a lot of potential for character development.
Like If Miraculous really WAS designed as Adult Show, Marinette would be prefect as a Good Example of What happened if the Wrong People get Powers (Or even how Marinette can be written as an Example as a 'She who fights Monsters type of person' where she's no better then Gabriel, Lila or Chloe despite she and her Stans being against them)
But on the Opposite side of things, Canon!Marinette ironically had a Lot of things that could work if she actually Develop as a character?
Learning to be more confident via being Ladybug? Having to learn to not overeact over the Smallest Flaws? And in General having Empathy towards others (Even her Bully whom she's not required to fix her but not swooping to her ?
All and more examples that if Marinette WAS allowed to develop and suffer consequences, She would be considered a Very Developed character, Especially if Miraculous is written less of whatever Astruc's writing is and more of a Coming of Age Story for Marinette form a Timid apathetic girl whom becomes a Confident Superhero who learns to care for others (And acknowledging that Chloe's a Bully but not swooping to her level of Pettiness as well)
Do you think if Marinette's not be such a Creator's Pet, She'll be the Prefect example of either a Cautionary Tale or having the Largest Amount of character development since Marinette's character unironically have a lot of flaws to develop form as well?
Like, my first instinct is to say "yes", based on the premise that Marinette's character doesn't otherwise change, but, like, IF Marinette wasn't a creator's pet Black Hole Character the universe revolves around, and was never intended to be that and the writers were actively avoiding doing that, when we'd instantly get rid of the worst of Marinette's excesses.
No more her treating like her problems are the most important in the world.
No more her insisting on having input in affairs that have nothing to do with her.
No more her crying the loudest whenever she's the one hurting people.
No more her constantly hurting people in order to center her in every single episode.
No more superhero team being run like a dictatorship.
I feel like, as soon as we remove "the writers know Marinette is the center of this fictional universe and write her accordingly" from play, Marinette becomes a lot more basic as a character. Suddenly her flaws would be learning to deal with her persecution fantasies and talking to people normally. And, like, yeah, that's not much, but at least it gives a clear line of what kind of development is needed.
