There is advantage here. Imagine being able to have a CI process for design files - just upload your sketch file's changes to the repo and this tool in your pipeline builds/deploys a version of this in HTML in your staging environment. Easy link sharing built in. If designers have the ability to work closer to the web, more power to them. It should be our job as software engineers to make this as easy as possible and this tool could be one specific implementation.
