Using a name like "John Doe" instead of the ID like "@johndoe1234" for YouTube comments

Question

Is there any way to revert the names that appear in YouTube's comment section to the old style? I mean, it currently shows just @[My Google ID], which is not so good, in my opinion, for people to remember and exposes my e-mail address.
