Can Jamstack be framed as a new way of working, similar to Agile, and what tools are emerging to support people working in a Jamstack way?

I think in some ways it's part of this larger trend pushing more functionality forward to the client. It is about technology: improving load times, improving security and making the end user's experience faster, better and more interactive. If it weren't for the constant pressure to innovate in terms of the user experience on the web, there wouldn't be so much froth in the JavaScript community and so many people trying to create new tools and changing practices every couple of months. It's just part of the constant evolution of the web, which is a very innovative and dynamic technology.
