Why not Standard, Pre-Release, and Development versions?
Is there any requirement that Debian releases _must_ be labeled Stable,
Frozen and Unstable?
IMO, those labels are misleading and/or unnecassrily pejorative.
Certainly, today, Slink is the current Standard Debian version.
Soon it will be displaced, as the Standard version, by Potato, which
hopefully will soon emerge from its Pre-Release lockdown.
Woody will stay in Development until it locks into Pre-Release.
Just a thought,
