The problems aren't insurmountable, sure.  They just add
complications.  In most cases, if you are aware a rename was made, you
can tweak the VCS commands to handle that.  But (a) you need to be
aware, and that is not always obvious; and (b) how to tweak the
commands is also not always obvious.  If you fail to notice and/or
fail to tweak the command as required, you might very well see
incorrect information and make the wrong decisions.  It happened to me
several times, so I'd rather we avoided that if possible.
