However, those are limited to the versions which the SDK is compatible with, e.g. SDK 1.14 only for FF 21 - 25.0a1 , SDK 1.17 only for FF 26 - 30. My questions are:

] | I assume your goal is true immutability -- each object, when constructed, cannot be modified. You cannot assign one object over another.
The biggest downside to your design is that it is not compatible with move semantics, which can make functions returning such objects more practical.
As an example:
```
