His post got me thinking about where I actually see the place for web components. Turns out that finding their sweet spot is hard:
- No interactivity (like typography): too easy with (BEM-style) CSS

- Templating: better handled by a CMS or SSG
For me, web components shine where the browser fails:
- (Dynamic) Alerts
For everything else, I'm weighing the pros and cons and the burden of maintenance and performance-loss more than ever.
