It gets really annoying to use any of them when they have name collisions. Especially extensions on Track or basic public functions. Also make some same-file extension function in the MangaUpdates package method on the class they extended. I would have done the same for the DTOs themselves but any that are used on method signatures have to be public and then all their members also have to be public. We'd end up with a confusing mess of some internal and some public DTOs, even at the top level (since generics can be internal to the `dto` package (e.g. with parseAs<...>) but return annotations cannot be).
