I can say that at least currently, there is no appetite for Perl attempting to "reclaim" the Perl 6 version in the foreseeable future. It would be a disaster in both community relations and marketing. It will either be Perl 7 or Perl 34+.
I have previously stated that I would like it to be an alias of sorts.
use v5.30;
use v2019;

Perhaps even something like:
use Perl v2019;
