It depends how really you use virtual DOM. React's "reconciliate whole world" approach can be excessive, yes.

But, for example in Sciter, vDOM works in [web] component cases that are similar to Svelte:

   class Beers extends Element {
     bottles;
     
     render() {
       return <span .bottles>{this.bottles}</span>
     }

     set value(v) {
       this.componentUpdate({bottles:v})
     }
   }    

When you will do

   document.$(".bottles").value = 12;

it will update only what is needed. Pretty much Svelte style but with the convenience of vDOM.
