I strongly agree with this.  It is simply impossible for many content
producers—for example, newspaper or textbook publishers—to release their
entire works under a viral copyleft license, but including a CC-BY-SA photo
with a mention of the license is perfectly acceptable.  I believe that an
all-or nothing approach here will elicit a unanimous "nothing!" from these
commercial content producers: requiring all reusers to release their stuff
under CC-BY-SA will be unacceptable, and so they won't use *any* copyleft
content.  We'd just be shooting ourselves in the foot.
