One thing taught to me by an accessibility advocate in a university was that accessibility isn't just for people who have sensory problems, Accessibility is about making things accessible for everyone. Given that everyone seems to prefer their own indent size, using tabs and setting the tab width in the editor is an accessibility win for everyone, not just partially-sighted users.

I've been a proponent of spaces until now because of consistency, but this argument has won me over to tabs.
