To my understanding, he's admitted his mistake. That doesn't mean that after this much time, going back is the best solution. There are major positives and negatives to all options, so at this point people are just letting it stay as it is rather than force it into something that could be even worse. People have had well over a decades to come to terms with the naming, and coming out with Perl 7 (or taking the name Perl 6 back) aren't really going to help with anyone that's already confused.
Perl 5 and Perl 6 are still both advancing on their own paths, it's not like either one was actually stopped because of this.
