FWIW, I have a simple key that prompts for a new name for the buffer.
I use it all the time, for *Help*, *grep*, *Pp Eval Output*, etc.

On the other hand, I also reuse the same *grep* buffer for different
searches, and rerun a previous search (in the same dir or not) by
retrieving its args from the history list.  I don't understand what
the missing feature is that is being discussed.  Why is it hard to
rerun a previous `grep' command?
