From a religious standpoint of someone that would consider the writings to be sacred and "inspired", the implications are greater.
A theological argument can be made for the JW perspective in the following way. When the church turned apostate in the second century it began to misrepresent Jehovah in various ways, including the demotion of his name, misrepresentation of Jesus as ‘God the Son’, the emerging Trinity doctrine, and so on. This infiltration of false teachings prevailed until the truth was revived by modern day Jehovah’s Witnesses. Although false Christians altered the text of the Bible in various ways, Jehovah ensured there was enough evidence for sincere seekers of the truth to derive truth from the Bible about God, Jesus and God’s name. Further to that, the discovery of the LXX fragments with divine name, from the 1940s onwards, prompted JWs to restore the divine name to the New Testament. The discovery of the Fouad Exodus fragments in particular arrived just in time when the New World Translation was being prepared. Subsequent decades brought more and more evidence for the continued use of the divine name, and a number of scholars came to the same conclusion as JWs about the divine name in the New Testament. Those who opposed the implications of the new evidence about the divine name were predictably Trinitarian scholars who resist the idea that Jesus is distinct and subordinate to Jehovah and that Jehovah’s name continues to be important for Christinas.
