in the Chinese Wikipedia an administrator had deleted part of article histories. He deleted the article complete and then reversed the deletion of part of the historical versions. He did this in good faith, because he deleted vandalism edits and copy right violation content. I was the opinion that this is not a good idea because at first the GFDL requires the edit histories (also of the vandalism edits) and second because thus we lost part of the records about the vandals edits.
In my opinion only the edits from which the current version is derived are obligatorily given. Thus, if an edit is completely removed, removing both the edit and its undoing from the history would not be objectionable from a licensing point of view.
