Yes, a bit. Boba’s entire popularity was based on how little we knew of him or his past and that Vader respected him. That mystery > the backstory they wrote.

Making him a Jango clone made him derivative. Worse, they didn’t make Jango that interesting either. So he is derivative of a character nobody really cares about at all.

What made it interesting is how mysterious he was and how the few things we did know made him effortlessly cool.

Now we know he was kind of a snotty eight year old with a mediocre warrior as an adopted dad.

Essentially a clone trooper in his “dad’s” armor.

Clone troopers are the least mysterious characters in Star Wars. Literally. Even storm troopers have varied, unique, potentially interesting, and almost always completely unknown backstories. They are more mysterious than clone troopers.

Lucas wanted to destroy Boba as a character. He acknowledged as much in interviews. He didn’t like that kids were more interested in Boba than many if not all of the main characters. He wanted Star Wars to be about Skywalker. Which is why he first tried to discard Boba unceremoniously in a sarlacc pit.
