I agree.  I think there's a bug report open for it.  It should be
possible to explicitly erase the individual flash segments, and the
default erase command (when issuing a -U flash:... option) should
probably not even be a chip erase but an application section erase.

I'm currently in the process of restructuring some of the Xmega
handling (which is one the remaining things I'd like to have done
before releasing AVRDUDE 6.0), and hope I'll find a nice solution to
the Xmega erase problem as part of this.
