Yes and (moslty) no. Cascading that reaches “outside” of its component to affect other things is bad. So it is all about your approach to the cascade. Most people who have been working on the front end still struggle to grasp the concept of encapsulation & isolation when it comes to their CSS.

In my experience working on a web app that sees +80k DAU, the most difficult updates to our UI are ALWAYS in the cases where somebody wasnt cogniscent of the cascade. Or was, and used it when they shouldn’t have.

IMO, theres a lot of pushback to this technique and not a lot of questions into its benefits, but plenty of questions as to why its “just like this” so “why should I use it.”

I encourage you to consider the benefits of an isolated approach to UI, or perhaps try building something with it and see how the method compares to your current approach.

Or, we can all go on assuming that Airbnb, Facebook, IG, et al, have all opted into this approach for no reason
