For someone who wanted to make Star Wars as "inclusive" as possible, Kathleen Kennedy neglected so many opportunities. For starters, we only ever saw one Star Wars character with any disability, and they used it to portray his villainy. No poly characters, no varying religious communities, heck they didn't even have any relationships between droids and organic life forms despite the Dr. Aphra comics trying to make it clear the Star Wars universe doesn't have our level of standards for what counts as an expected relationship. It's almost as if they weren't trying to be inclusive, just populist.
Those are injuries though. I mean like an actual medical condition, something like "that character has autism" or "this one has asthma". We only had one character with a medical condition that was something that wasn't an amputee, the guy from Rogue One who takes off his breathing mask to take his last breath right before he was about to die. They portrayed it as a dramatic extension of his villainy. "Diversity" in Star Wars is incredibly disappointing.
I mean yeah, they're disabilities in the sense that they're a condition one ends up with that challenges them in some way, but it's not something "wrong" with a way their body works, it's just a type of damage someone can receive. They're also arguably rather excessively easy to use as a stock disability from a storytelling perspective. Imagine if you were making a story and were compelled to give some characters some medical conditions to add to the depth of the story, and you thought "meh, we can just remove a bunch of their limbs". Or to put it another way, unless the person is a Cyanide and Happiness character, nobody is going to write a biography in their elderly years titled "My Life As A Guy With One Hand" so as much as someone might write one titled "Life As An ADHD Person".
I have the same semi-complaints (not really complaints per se) about Pokémon. There was one single blind character-of-the-day in the original season (because he was old), the manga version of Bryce was wheelchair-bound (kind of inevitable though for him), and the remake version of Wally was hinted to have asthma, but for two and a half decades of journeying around the world, there was never someone mainstream who popped up who had some kind of uniquely driven medical trait, which after so long doesn't make you complain but makes you wonder if they're avoiding it.
Missing an extremity is an actual medical condition... I get your point about other kinds of conditions that are congenital or otherwise not directly due to physical harm. PTSD would be a good example of what could have been included in that case as well (this might actually exist in some form from disney). With how poorly so much of it was handled, it's probably for the best that they didn't try to tackle autism or Downs syndrome at the same time though.
