What feedback, if any, should a program give to those artists who were not selected for a commission?

Many programs do not provide any feedback to artists who did not advance past the initial round of consideration. The large volume of candidates and the much smaller number of program staff members make this a logistical impossibility. However, it is common practice to provide some feedback to artists who made it past the initial round but did not receive the commission, particularly if those artists asked for criticism of their proposals.
