This is great news!
I have to mention that I experienced a bug using Guix on Debian not so
long ago that broke my Debian host install completely. I could only
restore my Debian system via snapshot after. This happened when creating
a Guix container and using Guix from inside it. May be worth looking
into fixing that before Guix gets included in Debian, as to not make a
bad first impression on possibly many Debian users.
