Then an alternative could be to make sure the client finalize properly

I understand. Modifying all clients would be heavy

Note this should be done in conjunction with both the CORBA and GIOP
see 8.5 for how omniORB proceeds
I imagine this policy would be sufficient for your needs, but it
depends on the ORB client you use
Implementing this policy in PolyORB would be technically possible, but
We can hardly commit any deadline for implementing it, but we can
provide guidance if anyone is
