That ensures the hex files are always on the same place so you do not need to mess with copying build paths into the programmer (if somebody uses an external programmer). Inclusion in the setup - it is up to you..
True but you at least need to select the HEX file once right?, so I think it is more work (because you have to select the correct hex file and browse to the path): 2012-08-14_1550
