iTunes hasn't been part of a default installation on any Mac I've used for almost two full years. It remained on my Mac when Apple released Music.app back then, but I simply deleted it and it hasn't come back since.
Because Music app is more or less part of the Finder now, it's not likely it will be an "option" to be removed.
