The existing arc/types.js file is sooooo close to being a typescript *.d.ts file.

I spent about an hour trying to hand edit types.js into a list of type definitions but didn't quite understand some of the types and structures well enough to do so (for example what methods should a type the implements node receive?). I'm also guessing the existing types.js file was procedurally generated, in which case it would be much faster and more maintainable for someone inside Shopify to update the generator once, but even if it was hand edited types.d.ts would still be an incredibly achievable super high value asset to the community.

What's the best way to go forward - should I take a stab at a hand-edited PR or would that be rejected because types.js is procedurally generated and types.d.ts needs to be as well?
