It's less likely (and really, depends on the quality of the team and their attention to detail—it's not a "law"), but certainly not a "no way." I'm far more concerned when the official answer to a feature missing is "just use a third-party!" That spoils a lot of tools for me as I immediately read that as "you're on your own, buddy, have fun with your Frankenstein app!"
Over time, unless the team building the thing is entirely tone deaf, I'd expect each individual tool to improve as demanded/necessary. Not only that, but knowing that those tools are being thought about as parts of a whole is deeply comforting (I trust them more than standalone tools as interdependency headaches have likely been solved).
One of the biggest headaches in JS is the tendency for tool builders to just eschew responsibility in favor of sending their community on a goose chase. I commend the Deno folks for taking this approach. We should have more, not less of this attitude in the ecosystem.
