If we know that old data was wrong, then we should correct it, but if we merely suspect that the old data is unreliable then we should retain our best estimate, not remove it.

So I support the removal, since I think the discussed data obviously appear to be of very questionable nature. We cannot even consider the discussed data as "our best estimate". Of course, there is no 100% guarantee - no black and white. If someone can know it better then it is easy to add the lost data again. But we should really not let the users in the state of wrong assumptions. Stability of data should not be the primary concern, rather correctness. And most users (near 100%) don't care about old that is to say archeological timezone data.
