It can re-request the lease based on how the interface is currently
configured using the -r option. It does not do this by default. That
should be satisfactory.

Hmmmm. I disagree here. Link managers, such as wpa_supplicant, should
call a generic network script to say "link up/down" and then either
configure static ip or do dhcp.

Gentoo uses this approach very well. Although I am slightly biased as I
wrote that part of Gentoo ;) This is going outside the scope of this
discussion though.

Great! It's currently being re-formatted so that it looks good in
editors that don't use my vim rules though.
