The customer is always right.

There are 3rd party developers who are working on plugins for Photoshop and Illustrator who have been requesting this in Spectrum CSS on this GitHub issue.

One of the benefits of systemizing design is that it allows us to introduce various “levers” we can turn on and off for multiple purposes. One thing we’re working on is the option of density for our components, which would allow products that need to utilize more screen real estate to do so where appropriate.

We also get to help products that joined through acquisitions (i.e., Magento, Allegorithmic, etc.) that have their own platforms, 3rd party contributors, and tech stacks.

First and foremost, we hope this positively impacts internal and third-party developers to ensure Adobe’s product ecosystem is serving designers and engineers working on our products and extensions.

Corporate systems have certainly changed the industry and influenced the evolution of design systems. They provide a common platform for design and engineering to create cohesive and intuitive products, and they have also helped to provide insight and inspiration for others. Design systems aim to solve very complex problems in terms of design, engineering, process, resources, and more. Seeing what large companies do and how they try to answer these common problems helps the community as a whole better understand the issues and potential solutions.

There are a couple of internal JS implementations like React and Angular and those teams are currently considering opening them to the public as well. Although it isn't currently optimized for emails, Spectrum CSS should give you a place to start.

Here's an article introducing the Spectrum Design System. It was written about a year ago but gives some good insight into its origin and the motivations behind it. https://theblog.adobe.com/introducing-spectrum-adobe-building-design-system-scale/

Maybe I should have used Show DN instead of Site Design. I still don't really get how this all works.

We're looking to help understand how we can best help improve design in open source, and we really need to hear from more designers.

Yeah, that's exactly our use case for now.
