Thank you, I'll wear the title of: leading critic of nesting proudly! disclaimer I'm not a hugely experienced programmer, but have done a few open source projects in Vue, React and am currently working on a series of Angular applications with a team at work.

In Vue and Angular component styles are automatically encapsulated at the component level by scoping (I think) so nesting isn't really necessary to target specific components. Angular also recently deprecated a method of breaking out of component styling and soon it will be completely removed from the framework.

Although I'm a critic I'm not totally against nesting, I just feel that SASS encourages it, so without discipline things can get very complex and fragile. One level of nesting is OK with me though I suppose...
