The reason for not exposing a public constructor is that this gives a little more latitude for building, in the future, a proper inheritance interface.

Factory methods are more versatile than constructors because they can return different class types. In the future, we may want to expose subclasses of Transliterator. Let's say that the transliterator 'NFD' has, in ICU, a specific C++ type (class) with more methods. With a factory method we can return a PHP class that exposes these additional C++ methods, while with a constructor we couldn't.
