I'm not cozy either.  And you've confirmed crystal-clear that the
exception is clearly valid in this use case and that users won't somehow
believe (or need to act) as if the reciprocal clauses in the Zero*
software would apply to the podling's release?

Agreed.  Including LGPL code in any Apache product release is not a good
idea immaterial of any explicit exceptions.  Merely because the
exception may technically make it legally compliant is not the point;
end-users will be surprised to see anything *GPL* in Apache products.
