Here's an unpopular opinion: it is unstable because we don't know what exactly "front-end" means. First it was static HTML pages, then it was CGI (ColdFusion & DHTML FTW!), then it was PHP, then it was Rails, then it was Node, then it was React, Angular, Vue... Those aren't random progressions. On the contrary, they are front-end devs responding to needs of the UX moreso than the UI. There have been major efforts to make reactivity match what the user is trying to do, but we're still in unstable-land because we're building the bridge while we cross (I hate that analogy but it is true).
