Neat.

Now add a way to hierarchically roll-up these micro-classes into semantic classes behind the scenes (Perhaps in webkit?). Compile things so you only carry-around the css micro-classes you've used, and make a flag to either deploy using the semantic or micro class method.

Best of both worlds. There are also some other mix-and-match ways of doing this. Where the real value is separating the tiny CSS adjustments you make from the business-class stuff, creating a middle tier (which this guy deploys directly)

It might make things easier. Or it could be yet another dumpster fire. I think it depends on how it's used.
