Can't we just use readFile and assign {} to data wen catching ENOENT?

Sure, the only anti-pattern is to rely on existsSync, as its result might be outdated by the time the readFile calls is processed.

Could you add a test that makes sure the parent package.json is updated when ran from a sub-folder?

corepack use foo@1
mkdir src
cd src
corepack use foo@2

LGTM.

NIT: This seems more like a new feature (feat:) than a bugfix (fix:).

I chose fix because it was already the intent of the code, as you can see the 'NoProject' string was already supposed to mark the creation of a package.json. No strong feelings though

Right, in that case I agree, it's a bugfix 👍
