You are right. In that case the reload won't work. The method is not 
restored with the previous version in the image.

No way to reverse that. But I think not a big deal for most of the 
packages, either there's no initialization or the package is initialized 
again.

The reload has exactly the same effect as selecting the package file in 
the Files tool, and using the Install button.

This occurred to me because after a system update, Cuis was warning me 
that some of my packages versions on disk didn't match what was in the 
image. But didn't provide a way of reloading. I had to manually find the 
location of the packages on disk, and install them again. It actually 
worked for my packages, but you are right that it cannot be guaranteed 
it will work for all.
