I don't think anyone disagrees with that at this point, but hindsight is 20/20.
I personally wouldn't mind if there was a slow shift towards using the current main implementation's name (Rakudo) or some other (NG Perl?) for the language down the line, but I think doing so before release would just make every problem worse, including Perl 5's ("Oh, Perl 6 is no more? It failed? I knew it would... Perl is a dead end.")
...with an exceedingly poorly chosen name.
(Which is not to diminish how good it is as a language.)
