If not, I don't see how the inclusions of stairs in general is an issue. If building designers aren't meeting ADA (or similar) requirements then that is a different issue.
While enjoying the brand-new library at Kenyon College, you are confronted with what SHOULD be a stairwell, but you can't see stairs, just handrails and a weird shimmery pattern where the stairs should be. Do you try your luck, and stick your legs out into the shimmer? Or do you search for the elevator?
In your example it might be difficult for such a person to identify the location of the stairs, but still very dangerous once they found them and began climbing. In my example-- say the stairs were a uniform red-- once the stairs were found it would still be equally dangerous to climb them, little better than going up blindfolded as you couldn't distinguish one stair from another.
A person with that impairment should probably want some sort of occupational therapy to use a guide cane or other method to safely perform tasks like that without relying clear contrasting colors.
Now, that said, maybe no one with Parkinson's should be going up any stairs of any sort. But I think glass stairs, even if frosted, would definitely be an ADA problem.
While I dislike the design, it’s generally not going to be at the cost of those with physical disabilities.
For some people, it's just harder to do everyday things. It doesn't mean they can't move around. And for people getting older or with a degenerative disease, continuing to do things normally is also a matter of pride.
To put it in obvious terms, it's like saying that we can add 3-4 stairs at the main entrance, because anybody who don't like stair can enter via the damp alleyway in the back, besides the dumpsters.

One that comes to mind is girls who wear skirts.
Disabilities are something I agree should be mentioned, but the GP beef should be with just mentioning clothing, not a subsection of a sex who wears it.
