I suppose it depends on who and where one is sending the requested documentation. Nigeria probably would not be a good place and maybe Switzerland would. The problem I have with this procedure is that it really is not necessary. Photocopies verify the initial qualification. Then the company sends for the applicant. If there is any discrepancy between the actual documents and the photocopies sent, it would be pointless to actually show up at the companies doorstep.
On the other hand, an actual license would be a great Master copy for possible conterfit usage. I never have had to and never would myself, but thats just me.
