def_domain_type can't be used for this purpose. But this seems to be a
temporary code, as it will be removed in patch 09/25.
It looked OK when I checked it, mkt_v1 is really confusing what it
tries to do, but it should call probe_finalize and basically do the
same hacky thing as what UNMANAGED was trying to accomplish.
Did you see something else?
No.
