It would really be nice if project owners could just do these deletions ourselves. Any particular reason it's not available? It seems a very natural feature to have and is often requested (in addition to generating extra work on the launcphad admins, who need to do this kind of janitorial work for the users of the sysmtem, the individual project owners).

Thanks in advance!
