I am inclined to say that it has no security implications.  You have
to be able to write a bogus loose object in an object store you
already have write access to in the first place, in order to cause
this read-only access that goes beyond what is allocated, so at the
worst, what you can do is to hurt yourself, and you can already hurt
yourself in various other ways.
