Yes.

The contents of the package get overwritten, the new classes and methods 
and renamed classes are deleted.

Yes, that's what I'm trying to prevent. I feel like it would be good to 
have even if the reload doesn't work and you get inconsistencies. In 
that case you should start with a new image. But if it works, then you 
didn't need to start from a fresh image. Responsibility is on the user.

I don't know ...
