The dumping is code is short and straightforward. The loading code
would be slightly more involved, yes, mostly because of patching
pointer target addresses between all the structs, but still I think
it's a reasonably small task.

Gengtype dependency is a kludge. But since plugins need access to GC,
I really don't have any better idea.

Debugging dump support is the closest thing to "gengtype improvement
wrt plugins" there. Not much else.
