The question is: is it more common case to have very large number
of heavyweight tags, or is it more common case to have very large
number of lightweight tags (refs to commit objects).

In the latter case the solution to not trust lack of dereference
means no gain in performance (although for the core checking type
of object is faster (much faster?) than depeeling tag, so the gain
wouldn't be large), although the solution is probably safer.

Still, the decision: do not trust the lack of dereference in
packed-refs, or mark packed-refs as having dereferences and trust
lack of dereferences, is fairly orthogonal to the format for depeel
in packed-refs.


P.S. I have just noticed that you have taken the discussion
off-list...
