Feature summary

In Special: Delete you should be able to access protection options if you have the required user right (protect)

The way to do would be to also include a section in [[Special:Delete]] that duplicates [[Special:Protect]] if the required user right is possessed by the editor concerned. The special page would make then changes to both the deletion log and the protection log.

Benefits

Any administrator who wishes to "delete and salt" a page would be able to do this in one move, rather than having to take 2 separate actions to get it done. This would be more efficient.
