I tried to address this in the attached documentation patch.

The idea is to:

* Recommend it for new packages in the 'guix' channel, mostly during
  patch review.
* Once we are confident in the implementation, remove the "experimental"
  status and recommend it in the documentation.
* Merge pieces of it into python-build-system as we go, such as sanity
  check changes, using python-toolchain, etc.
* When we "know" that there won't be any major regressions, swap out
  python-build-system with pyproject-build-system entirely and mark the
  latter as deprecated.

Thoughts?
