I would say that A007516 is clearly erroneous.  Compare A014221.

Are A004249 and A007516 really the same sequence, with an erroneous 
number for
a(0) of one of the sequences?

Or is there controversy as to whether a exponent-tower of zero 2's is 0 
or 1?

Still, in my opinion, there should be a comment at each sequence at 
explaining the controversy over the 0th term.
