You have to ask yourself why we were removing inline styling and inline JavaScript. There is a performance argument (inline styles perform badly), but the main goal was maintainability. Now we have ways to use these patterns and still have them be maintainable, which means it's time to reevaluate that previous effort. Co-locating styling with structure and behaviour tends to make our lives easier. I can go one step further, I work on a React-based website which achieves straight 'A's on webpagetest and scores 100 on Google Pagespeed (Mobile and Desktop), this took far less effort than it ever took me to achieve worse results on previous stacks. The component model (with co-location of styles) is incredibly powerful, and it works, give it a try.
