Just pretend that magically everybody knew how to code. Wouldn't designs just be done in the browser? No longer do you have to maintain these design artifacts post handover. There would be no unrealistic designs that do not consider the constraints of a browser window.
I know this is unrealistic but I often think about this.
This change to Figma makes me less likely to choose it as my primary tool either as a designer or a developer. Though I guess this is a minority position as I'm compelled to use it all the time as Figma's become a kind of defacto standard in many sectors these days.
