See my intro in the parent issue (see VWR-1825).
This is sort of a followup on VWR-1752 where I mixed two issues (objects and landmarks).
Basically in the UI triage there was some consent that this may be desireable for wearable attachments, but entirely undesireable (with experience from past event) for other objects, i.e with regard to the so called box-head phase or accidentally wearing houses or boats.
I will check the source code and will see if it is possible for an object to determine if it has a been worn before or has an attachment point assigned in order to discern houses/boats from glases/cigarretes/guns/animation-overrides, etc.
