I'd also consider myself not a "framework guy" -- Spring is not my favorite, I pick flask/sinatra over rails/django, servant over yesod, vue + vue-router over ember (these days) etc. Maybe the distinction is that it really matters which framework, and how it's put together, and how much you have to commit to use any of it. I think the commenter's question was really more about the diaspora of these tools and why they all exist -- svelte is pretty decidedly not a framework (in fact I don't even think you can make it one, AFAIK there isn't like a "svelte data"). IMO the only full blown frontend frameworks are Ember, Angular and react/vue + react/vue-router + flux-y pattern data store.
