It is a good concept. As best as I understand it (I'm still learning), the existing grammar for standard names doesn't allow a qualifier of this sort. Qualifiers are not allowed to change the units of a quantity, for one thing, and a binary mask qualifier doesn't fit into any of the existing qualifier categories. That doesn't mean one can't be developed, but the usual way this is handled is to just request a new standard name.

The product is derived from the IMS Daily Northern Hemisphere Snow & Ice Analysis. It is a grid in which cells are marked as snow-covered or not snow-covered. The GCMD already has the keywords "Cryosphere > Snow/Ice > Snow Cover" and "Terrestrial Hydrosphere > Snow/Ice > Snow Cover", which are applied to the source product.
