> Bootstrap and Sass already solve this problem for the web.

In a vacuum, sure. But products aren't all built in a web-centric vacuum.

> That's irrelevant, isn't it? I mean, do you run apps straight out of Sigma/Sketch/Framer? Do you also think it's reasonable to call out Photoshop/Gimp/MSPaint?

Figma/Sketch/Framer are design and prototyping tools. They are _very_ relevant in how we build products. The back-and-forth between design and engineering leads to better outcomes if both sides speak the same language, and their tools allow them to do so.

(Photoshop/Gimp/MSPaint aren't so relevant un product design)

> Do you think it makes any sense to bundle everything together?

Not everything. You generally want folks using your products across iOS, their car, their TV, and a web browser have a coherent experience. This doesn't mean that everything needs to look exactly the same. It means that key design decisions can be distributed across the board.
