Alter objects get garbage collection and thread support from Perl, the class has nothing to do with that. Destructors can be freely used for other purposes.
An Alter-object carries all its data with it, ready to dump and able to be restored

I think these are only true if the object reference is a hash/array that stores the references for each class. If so, you give up encapsulation and the ability to do "black box" (aka "foreign") inheritance.

If Alter uses inside-out techniques behind the scenes and the object reference is a key into data storage maintained by Alter with the references for each object for each class, then you still have all the garbage collection and threading problems inherent to inside-out objects.

Even if you use Hash::Util::Fieldhash, that just pushes the issues into the Perl core and it's not backwards compatible before 5.9.4 (at least, I think not).
