It was. The ADA was the result of an enormous amount of struggle and activism, and that movement continues to the present. Reach out to a local disability rights organization (I guarantee there's one near you) and ask if they had any concerns about office work before Covid. I'd also recommend the documentary Crip Camp if you're not familiar with this part of American history.

Edit: Here's an article from the start of the pandemic with lots of quotes relevant to your question. Sorry for the archive link, the site seems to be down right now.

> Watching these accommodations become available in a wide-spread way so quickly has been really painful. It hurts not only because I could have benefited from accommodations like this throughout my education, but because there are so many others who could have benefited, or were forced to drop out of school, or quit their jobs because their school or employer told them they were impossible to accommodate. These accommodations have always been possible but acknowledging that requires acknowledging the ableism behind their denial.

It's a quick read and it's very good, I recommend reading it. Most of the issues discussed could be most easily addressed by allowing full remote work. Also, many of the people quoted have "invisible disabilities" - you may have coworkers like them without realizing it. This isn't just about ramps and elevators and other common accommodations.

If everyone has more flexibility, I don't need to risk my job asking for reasonable accommodations.

It also helps stomp on stupidity like requiring 14 people in a remote office in the middle of Nowhere, Midwest to wear black tennis shoes. (I own no tennis shoes and can't wear them.) There was literally no reason for it except to have a dress code.
