Thanks! the GitHub page includes a lot of (imo) essential information that should be included on the site. The developer clearly did a lot more research than I assumed.

That said, one thing to consider if you're using this stack is that this implementation will produce OS specific designs. The fonts in each stack differ significantly between operating systems, which means that testing for each OS will be necessary. I already have an issue with the same fonts looking different due to different rendering methods in each browser/ OS.
