Media features are not deprecated. In @media (min-width: 30em) {},
'width' is a media feature. Using media features in a boolean context
such as @media (inverted-colors) {} is not deprecated either.
Media features query characteristics of the device being used and of the
environment, whereas @supports queries support for CSS properties (and
possibly in the future other CSS features like at-rules). They both have
their use.
However, one unresolved issue is that some contexts like @import accept
a media query. We’d like to be able to have any kind of conditional rule
there but are not sure yet what that would look like.
