We can not safely remove 'manage_afterClone()'. This can have a lot of 
unexpected behavior for different portal types.
'reindexObject()' anyway will be called (at least that I observed) for 
every object installed from bt file.

That's correct and it's one of the reasons I think we shouldn't remove 
the call to it.

The main problem in finding a general solution is that there's a 
difference between creating an object from scratch (i.e. using UI or by 
script) and creating an object out of a business template. This 
difference becomes apparent for mentioned use-case ('Person' object).
And unfortunately  'manage_afterClone()' is not aware of that fact.
One way is to pass another generic argument to it indicating that we're 
installing the object out of a template. This argument will be passed to 
the responsible portal_type script which for Person is 
'Person_afterClone' and in this method we can implement specific logic.
