Absolutely, and "higher signal-to-noise-ratio" is something I'd count as a selling point. However, I don't believe fewer characters necessarily result in a higher ratio. So in the case of two-way data binding, if I'm trying to trace how a certain value was be modified, data flow in the opposite direction might count as "noise", in terms of extra cognitive load. Again, this might not be something that is the case for Svelte, but it's what I observed in Angular.js.
