Yes, I understood that. My intention is to notify the user about the deletion but not
really want to revert the file. Emacs provide other options other than reverting. A
"revert" here might mean "close this buffer". However,this might need further
modification to notify the user about the deletion instead of the normal modification
notification. Using the original `ask-user-about-supersession-threat' might be a bit

confusing if file is deleted. What do you think?

There is nothing to revert from. A buffer visiting a non-existing file
isn't an error condition, saving it will not lose anything.
