I agree with most comments which say that the modular approach is good for maintainability. But what about performance that takes a hit when the JS is creating and linking styles. Also, browser caching of styles is not possible in these cases.

I would not care too much about performance in the context of linking and evaulating css for modern browsers. It has small if any impact. If it is better for maintainability - than it is good way to go.
