Early growth is typically more important than scaleability. What&#x27;s to scale if you don&#x27;t have any customers? It will probably cost more in the long run to achieve the same goal, but that assumes you make it to the long run from both starting positions.<p>Regardless, I don&#x27;t think the causality exists to the extent you&#x27;re describing. It&#x27;s no different than any open source dependency. Sure, I know how the functions in underscore work. That doesn&#x27;t mean I need to take the time to roll a deep clone. Saving time and money doesn&#x27;t imply cheap and broken.
