Yes, but styles can be applied and unapplied easily.

Would an API that you call from script that allows you to determine
if a given media query matches the default view be sufficient for
your needs?  That seems like it could be more useful than an
attribute that simply prevents scripts from executing, and it avoids
introducing similar-looking attributes that actually behave very
differently.
