To make Widget View Modes Interfaces [1] redundant, we would like to
propose extending CSSOM Views' matchMedium method to have a callback
as a second argument.
This would address the following sections of [1] in the following ways:
# 3.2. Media Type Changed Event Types
styleMedia.matchMedium("screen", function() { alert("no
longer screen!") })
# 3.3. View Mode Changed Event Types
styleMedia.matchMedium("(viewmodesyntax)", ... )
# 3.4. Resolution Changed Event Types
styleMedia.matchMedium("(resolution:300dpi)", ... )
# 3.5. Orientation Changed Event Types
styleMedia.matchMedium("(orientation:landscape)", ... )
The proposal has it's origins on the Mozilla bug list (see comment
from David Baron):

Kind regards,
Marcos
