Okay! Typical. 
I think it’s I’m just used to people suggesting that anything that’s not able-bodied white straight cis male seems to require justification, as if said fictional man is the default, and everything else must only exist if relevant.
And my first reading of what you said, was along those lines! BUT it can just be, think of how this impacts your character. Your protagonist who uses a wheelchair, likely won’t be hopping over a wall, but that doesn’t mean the zombies are going to eat them.
I thought you did it well. It fitted for her, without it ever being a case of “oh no we can’t put Heather on watch, or make her responsible for anything, because of that ADD she has.” It was never a defining personality trait of hers.
Oh! And just remembered another story about a teenage wrestler who’d won all his matches.
Debate rages over whether or not his disability is an advantage on the wrestling mat. Being legless gives him a low center of gravity and makes it harder for opponents to grab him, but it also deprives Hawthorne of the ability to arch his back to avoid pins. - https://www.washingtonpost.com/news/morning-mix/wp/2016/02/22/this-teenage-wrestler-has-a-perfect-record-and-a-state-title-he-also-has-no-legs/

Slightly on topic. Human echolocation - Wikipedia I know, it’s the exception not the rule.
But, what about being better able to navigate in the dark? Or immune to flash grenades and other powers that render people unable to see? Or immune to any sort of illusions, since they generally rely on visuals first and foremost, but if you’re paying attention to other things you’re less likely to be tricked?
If you don’t want to be all Daredevil, or even Geordi, how do you think it would work?
Depends on their reason for being in a wheelchair. There’s some wheelchair users that are far more athletic than I am. There’s some expensive wheelchairs that are suited for going over all sorts of terrain. Also push to near future and skip the electric wheelchair and mobility scooters reliance on battery and you remove other problems.
Of course there’s others who use wheelchairs where that’s not the case. But even then… Barbara Gordon as Oracle! Professor Xavier!
Long John Silver, complete bad-ass, uses a crutch to get around. (I’ve actually really enjoyed how Black Sails has been tackling Silver losing his leg, because it’s not been as simple as just getting a prosthetic, and it has impacted him.)

I think Zachary had good intentions.
BUT
I really disliked how Heroes Rise: Redemption Season portrayed disability, in regards to Starsoar and his mental illness. I found the whole plot-line extremely triggering.
That the sister’s storyline was focused upon you working to get a cure for her… as opposed to her doing it for herself… and that it was super-powered based. I didn’t actually play much of Redemption Season. There’s a lot I’d need to unpack about it.
And of course there’s Black Magic and their room full of mentally handicapped people that they drain life-force off of…
Fumbles though, guy with prosthetic legs, I think he was fine.
