>  I don't believe MQ features can have multiple values (i.e. it's not possible for the UA to set nav-controls to {back, share}, and have the queries @media (nav-controls: back) or @media (nav-controls: share) both succeed).

That is indeed possible: any of an MQs values might be true or false, with no exclusivity implied.

@SebastianZ's comment correctly explains how to combine those to get the precise boolean conditions, if desired.
