No support, for several reasons.
- If I'm hunting for WWs it's because I want a WW, not a 2+ gen.
- Wolves need to be removed from the system for performance/data/back-end stuffs
- For lore reasons or other personal reasons, if I release a wolf, I want it released. If I wanted someone else to have it, I would've sold it instead
- If the previously released wolf magically turns into a WW rather than a 2+ gen, it'd make previously KS or MM-exclusive breeds readily available as WW (for free!) which completely ruins the point of having KS and MM exclusive breeds.
