So? The only people looking at your html classes are you and your team. Bots don't process css, and most people don't look at html.

The same people looking and working on the CSS are the same people looking and working on the HTML. HTML full of long complex class names is a bit harder to grok.

I actually prefer nice semantic HTML but I admit that's not always possible.

I wouldn't recommend long and complex names either, but with something like tachyons, they're not long or complex, there are simply long lists of orthogonal classes.
