Newtypes aren’t hacks, they’re perfectly acceptable in my opinion. Especially if you’re willing to also use a crate like `derive_more`.
In my experience using newtypes like this causes a constant shuffle between the original type and the newtype.
If a library exposes Foo and I wrap it in MyFoo implementing some trait, I need to convert to MyFoo everywhere the trait is needed and back to Foo everywhere the original type is expected.
In practice this means cluttering the code with as_foo and as_myfoo all over the place.
You could also impl From or Deref for one direction of the conversion, but it makes the code less clear in my opinion.
