It is impossible if you're being responsible. You don't choose a technology that could potentially block you from solving problems in the future unless it brings a huge value to you.

Elm's value proposition is mostly being a functional language with an opinionated MVU library baked in, so you can reproduce that value with a better functional language and selecting a similar MVU library in that other language, which means it should never actually cross the value bar above the risk it brings if you need a browser feature it doesn't support and actively prevents you from accessing.
