I expect exporting from Sketch/Figma into React components would be cumbersome in this same way.
If I may pose another example from my days of industrial design, Rhino is a great tool for rapidly iterating designs and building CAD for renderings, however when your design is approved you really need to rebuild it in Solidworks for it to be made.
The real solution here is for companies to adopt a Design Ops/Design Systems Manager that can design and code in the front end. This would remove burden from the engineering team so they don’t have to worry about doing tiny design tweaks, etc.
