Hi,
- It also means we create an option that will get deprecated once v2 is phased out so we are adding a "temporary" option for users to "keep creating v2 addresses" but then will be useless and we'll deprecate and get a whole lot confusing if for instance v4 or v5 happens in the next years for X reasons (unlikely but not impossible).
It could be useful to have a standard transition/upgrade path when releasing new versions after v3. If we know that in the future we will have v4, v5, etc, we could design a more general process so users know what to expect, can plan for future releases, etc.
All best, Chelsea
