Looking in the diretory dtc is invoked from is not very useful behavior. As part of the code reorganization to implement this, I removed the uniquifying of name storage -- it seemed a rather dubious optimization given likely usage, and some aspects of it would have been mildly awkward to integrate with the new code.
