As far as I know, there are no groups or organizations that have adopted "Perl6" other than hobbyist clubs. It is not a production-ready language, still breaks backwards compatibility with new releases, has a dearth of library extensions for doing real work, and is orders of magnitude slower than using Perl for the things it can do. It's an interesting project that has attracted some very bright minds over the 20 years or so it's been talked about, but it really doesn't have much to do with Perl other than its unfortunate cooption of the name.
99.99% or so of the discussion in this Monastery is about Perl 5, because that's the actual practical programming language that we mostly all use and love.
The way forward always starts with a minimal test.
