Nice idea but there is absolutely no way that the name Gutenberg will disappear, especially if the official alternative is calling it "the editor".

You can't search for "the editor" in Google as its too vague. It's not clear to the millions of existing users if by "the editor" the writer means the original editor or the new editor so every article would have to say "the editor" and then say "you know, the Gutenberg 'the editor' editor".

I can't see it happening. It would be stupid of them to try to force it. Gutenberg is a great, unique, name and it lets people embrace it and discuss it and advertise it easily.
