Hey thanks. I think probably our experiences are just different here. I've found that convention (one css file next to the JS component in this case) is sensible but can break down over time or with larger dev teams. In these cases, I tend to prefer a technical constraint over convention when there is a choice between the two and it's for something important. On tracking down the styling, we haven't found identifying the relevant component where CSS lives difficult in practice but I can see that might not always be the case.

Edit: just to add, the comment in this thread https://news.ycombinator.com/item?id=19608498 does a much better job of explaining all the benefits of CSS-in-JS.
