I think that there might be a fundamental missunderstanding here: I'm not saying that we shouldn't use tabs to accomodate people with disabilities, I'm saying that better editor features seems like a better "solution" to the problem.

In the abscence of editor improvements I agree that it makes sense to use tabs to accomodate disabilities, I just don't think that it will catch on that mutch. I don't think that spaces (imo) being slightly better is a good reason to not accomodate dissabilities by using tabs right now, but I do hope there is a more editor oriented solution some day because I think it would propably be better both for people with visual disabilities and without.

Being in a slightly argumentative mood might have led me down towards validating this false dicotomy between editors and tabs, and I apologize for wasting both our time because of this.

You do have a point that I personally might have more influence over if a given project has spaces or tabs than if better editor features are made, but I think that there can be a point to having the poor support for programming that is apparently offered by screen readers to take some place in the discussion as well since that is a potentially more important piece of the puzzle.

I can't imagine that there is much of a point to keep replying after this so I think I'll leave it here.
