Not sure if you're familiar with the movement, but standardized design tokens[1] seem like the future to me, depending on how well they are done. There's a list of major vendor like Adobe, Figma, etc. that are already onboard and the standardization process is progressing slowly but surely.
As I'm designing an app I don't want just click & drag visually to get some eye-balled spacing or size value. I want a design system with consistent spacing rules. Design tools enable this somewhat but the token standardization is pushing this much further. For example: there's already a hub/API for distributing design tokens to other services. I've seen a live demo of Specify[2] pushing token changes from Figma to a GitHub PR or creating JIRA task during a design token talk from a token w3c group member.
And it's not just about design -> code. If these tokens are standardized, design tools themselves (among others) could have a standardized way of transferring designs.
Heck, even Utopia could embrace this at some point to provide you an alternative view/workflow for your already standardized design tokens.
