The short answer is that Xach's test case actually revealed that the reuse of old component objects could leave ASDF in a very bad state (modified components with some old attributes, components that were obsolete retained, etc.).

Don't do the write-up just for me.  It looks like you have good reasons 
for this change, and that other solutions would be unnecessarily complex.

Thanks,
