- A lot of things don't make sense to be cloned; anything that talks to an unmanaged handle, for example
- Most objects do not need a clone facility
- Deep-copying something properly is really hard if you go outside of a few simple cases
- In many cases, there are better metaphors than blind clones
- Manually adding a clone facility to your types that need it is trivially easy
To me, then, it is a no-brainer that this should not be added to the public API by default.
