RE: IEC60320
A number of inlets have provision in their design for double pole fusing but can be purchased configured as single pole fused devices. In this configuration this does provide a convenient location to supply a spare fuse. Over the years we have frequently done this on our products.

RE: IEC60320
IEC 60320 is a standard for the appliance coupler (male and female, cord and chassis styles) in assorted configurations (to cover assorted ampacities, temperatures, 2 or 3 wire) and does not include fuseholder specs. See UL 512 or CSA 39 for fuseholders, I don't believe there is an IEC fuseholder standard, but there is IEC 60127 for miniature fuses. I don't understand the risk you claim to introduce. You are not obligated to provide a spare fuse, but providing it would reduce risk.
