I agree with you, but this is a general issue with circular dependencies
(and circular conflicts) that they can only be fixed cleanly by
updating stable and not testing. 
That is why I have always strongly recommended to avoid them.

(We could of course fix it in testing by renaming libgc1 to libgc1c4 or whatever
but that would create a much larger disruption than removing a useless Conflict
from stable).
