Yes but it depends which changes he is doing. Imagine a change that break MC.

If it is possible to make the change in the image it is possible to make it in MC. ��One can always order the changes into a set of package versions that can be loaded, even if each package modifies only one method. ��One has the post-load script as a place to change things after snapshot manipulation, etc. ��I don't believe that MC can't operate on itself. ��We do this constantly in Squeak trunk. ��We have yet to break MC such that it can't be updated.
