🔔 @sandersn — there are no owners, but it would still be good if you find someone to review this PR in the next few days, otherwise a maintainer will look at it. (And if you do find someone, maybe even recruit them to be a second owner to make future changes easier...)

[andrewbranch]

Want to mention "exports" too? If the implementation package.json has "exports" with subpaths or conditions, the DT one should mirror that structure as well.
