If 'none' is a supported value (and it must be if "finishings-default" uses it, just like any other xxx-default attribute), then it MUST also be listed in "finishings-supported".
It is conceivable that there might be a printer that always performs some sort of finishing, for example cutting a sheet from a roll, but most of the time I'd expect a printer that supports finishings to also support 'none'.
