Plus if the author is keeping to go versioning standards they'll probably also keep to go compatibility aesthetics which bodes well for the future.
It's still a risk, but in this case one I suspect I'll also take next time I need to add a build step to a JS project.
It's not the usual JS personality screaming "wEbPaCk iS dEaD!!!lol" it's clear the author is thoughtful (observable via the project itself, the docs, and how he interacts with people in Github comments).
Restored my faith quite a bit.
