Even though I'm a relative newbie to OSM (&  and very much to this list)
I think that this kind of activity needs to be discouraged.

I think this is highlighting the need for an improvement being discussed on the main talk list ...

It is interesting looking at the history for some changes and seeing what 'collateral damage' is being done to additional information by people who have yet to fully get up to speed with all the finer points of editing. At least the addition of a tag which links the deleted or earlier related material would allow others to backtrack and 'repair the damage', perhaps we need a merge tool so that tags from the older id's can be restored to the new one? Whilst scanning history I've noticed many places where items HAVE been deleted and replaced with in essence the same item, but with things like disability access lost.

Personally I would prefer to see 'delete' removed altogether, and replaced with 'end_date', since in many cases the historic information IS as important as the current view. Current map rendering simply ignores anything with an end_date older than today, but we can still render maps for previous time frames :)
