When it's good enough. Right now I'm certain that I will change most things, so, it's not very viable. The bindings in particular are tricky, it's hard to decide what to do, and to avoid conflicts.

It doesn't have to be a distribution, though, just a set of configs. It's kind of a shame that the Guix package manager isn't universal, because that would be the best way to distribute that, because you can manage all of your configs from one place, with that Guix Home thing.
