I think the point is that Tachyons should be good for 90/95% of the styling you want to apply to the site. I think the creator would be the first to say that if you need something specific which Tachyons can't do you should do that but it doesn't make Tachyons redundant.

Personally, Tachyons still provides me tremendous value even though I sometimes have to write custom classes. I'm also often surprised to find that something that I thought would need a custom class, could be done with Tachyons when I dug a bit deeper.
