I don't quite understand this point. Perl has a major version, Perl 5. They want to offer a new major version, Perl 7, now. If Ember has already release a couple of new major versions, then why not learn from it? Maybe the Ember approach doesn't fit Perl, but without taking a look we won't know.
Also, based on the GP, it seems like Perl is planning something similar to what Ember has been doing: They are planning for Perl 7 to offer no new features, just change behavior. Then users can take their Perl 5 software and try it out with Perl 7 to see how much work it is to upgrade. Or they comb the source code to look for constructs that are deprecated.
