There is a very interesting use case where TLS is an overhead related to
video streaming over HTTP/2. MPEG DASH provides DRM encryption for video
content. If you transfer DRM encrypted MPEG-DASH video over HTTP/2, you
will have double encryption, which is clearly an overkill. Generalizing,
when you need to use Digital Rights Management, there are no additional
benefits by encrypting again with TLS.
