Four years ago? When Svelte was still in it's infancy? You're absolutely right to have received pushback for that. I would still consider Svelte somewhat risky today. You're lucky that Svelte has taken off but it could have easily been abandoned and you could be stuck with an outdated framework. Three years ago, someone at my company made the bad call to use Aurelia. It didn't take off, and we are still stuck with this decision. I'm not claiming that the success is random - Svelte is clearly a far better framework than Aurelia. But the weaknesses often become apparent only later into development, and so it's safer to bet on established approaches.
