You can always make the case that what ever need is felt/expressed by a
community is not enough. While it would be useless to point out that
copyleft is more needed (i.e., if encoded would be used way more often)
than 99% of the the whole reportoire of Unicode (like U+A66E, which is
used in one single word, a weird one, too, and only optionally…), its
usage is less massive than the symbols of the Creative Commons licences:
the cc-ring symbol itself, and the symbols for its clauses: "share
alike", "non-commercial", "attribution", and "no derivative works". See:

I don’t miss these symbols terribly, but then again I never cared for
the disunification (or non-unification) of "©" and "Ⓒ", "®" and "Ⓡ", and 
"℗" and "Ⓟ" — so I calmly use instead "ɔ⃝" (copyleft), "㏄⃝" (creative 
commons), "⟲⃝" (share alke), "$⃝" (non-commercial), "��⃝" (attribution), 
and "⊜" (no derivative works), in spite of the inadequate semantics.
