The problem is that this single "realistic case" is not actually very
common, and it's dwarfed by the other realistic cases: developer
forgets to use 'git mv' to rename the file; developer accidentally
deletes a file, commits, and then readds it later; etc.

Have I been bitten by exactly your example?  Yup.  But I've been
bitten by lots of other related things too, and explicit rename
tracking (at least in svn) has quite frequently made the problems
*worse*.  In my personal experience, git screws up less often.  The
fact that it's also elegant is a nice bonus too :)
