Isn't this same as:
missing = mandatory & ~requested;

Since "unsupported" use same logic, it can be easier to understand this way.

Or just putting following comment may be useful enough:
"mandatory subset of requested subset of supported", assuming it is correct :)

Fair enough. I'll prepare v2 then.
