Svelte is very new (a year and half of meaningful adoption).
React, Angular, Vue.js are the most popular, in that order.
I hate to say might=right, but for a project like Wikimedia, choosing a mature, popular framework is important.

It was a hulking, omakase, MVC? based framework at a time when the oppo was Angular 2.0 & Backbone.js and people still used Bower, then React threw everything on its head in favor of component libraries while NPM came into the mix.
They eventually refactored in components and I think repackaged everything for the new js fe ecosystem, but the battle was already lost.
It didn't go anywhere. Vue.js just became more popular for whatever reason.
