The question seems (in my opinion) to be whether registries are delegating 
netblocks that can be further subdivided, or not.

That is, some ISPs hold that if a registry has allocated /16s in some 
space, those allocations should not be subdivided by the allocatees.  If a 
registry is allocating /19s minimum in some other space, then the 
allocatees cannot and should not split that space and advertise longer 
prefixes.

In practice, how have corporate divestitures been handled by the 
registries?  Have organizations with portable netblocks been able to split 
them up and get new allocations from the registries, following the 
corporate reorganizations?

Surely someone on this list has worked through such an event.  How did it go?
