I don't see a problem in adding this functionality, as long as there are 
checks in place to be sure you aren't inserting a null map and the other 
regular forms of java sanity checking.  Be sure to test your theory 
extensively before uploading to the trunk.

As for the performance aspect, it sounds like a very complex way of 
removing metadata but I have not really tested any this or any other 
ways of doing it.
