Emacs doesn't do anything like that anywhere else, AFAIK.  Not even
auto-revert mode does something like that for deleted files.  I'm not
sure I see good reasons to do anything in this particular case.

Let me turn the table and ask you what kind of trouble you saw with
buffers whose files were deleted by Git (or any other VCS)?  Why would
you like Emacs to do something special in this case?  An extra buffer
is a non-issue in Emacs.

Thanks.
