But wouldn't an underrepresentation of disabled people be cause for concern in the industry? There are more legally blind people in the USA than there are Native Americans yet at the political stage there is very little interest in coming up for those people.

Several impressive videos on social media have shown that programming without using vision or even hands is perfectly possible, there are very few good reasons why such underrepresentation shouldn't be corrected for. In fact, I believe for many disabilities a job in fields like data science or programming would be much easier to adjust for disabilities than many other sectors where interactivity is key.
