He said he want to date a delete request. So to me all the above seems a very complicated and unnecessary.

I could understand the hassle, if he had asked about cleanup or citation needed request, where further changes to the page are possible and will effect the time stamp.

In which case depending on how big your wikia is and how "accurate" you want to be, i'd suggest not to reinvent the wheel and use something simple and already established like Dated templates.
