Correct me if I'm wrong, but isn't it just a strange coincidence that
InstalledPackageInfo is serialised in the format similar to .cabal
format?

InstalledPackageInfos aren't supposed to be edited by hand and do not
need good error reporting. They can be serialized using any
serialization library.

(Then again, "any serialization library" like aeson would probably bring
more dependencies than you're considering...)
