I felt existed with the current deletion-related policies, that there's no easy way to revisit a deletion that's been closed like this and to challenge votes made without any significant justification provided.
That's the whole point, if there's a Wayback Machine link that shows it was popular there's enough justification for undeletion, but if justification with extra info wasn't required all deletions would be contested by people who are trying to get something into Wikipedia for their own purposes rather than creating an encyclopedia. A safeguard is needed.
