Nice!

And it behaves as the non-lazy one.

There are a few things to change GUI-side to avoid an unnecessary loading of the complete ancestry of all the packages in the image, but this is workable.

I see two ways of using it:

as an "install, flush package cache before release and gain 5MB of RAM". If you start regularly developping (loading packages, etc...) then new packages will revert to non-lazy version info (without: 'please wait, I'm loading ancestry' moments).

as a permanent change in MC. The change is a bit more intrusive (need to change how working copies are created) but, well, as long as the worked on packages are inside the in-memory MC package cache, behavior is exactly the same as a non-lazy version info.

As you prefer.
