Consider Warning on Later Version Conflicts when Reindexing

[theory]

When reindexing, maybe just warn on later versions with lower numbers, since those likely predate the requirement that new releases have higher versions.

Removed all the version checks in 9f8cfc1, so this idea is no longer relevant.
