I can't speak for the designers but I can say what I did in the past
to try and alleviate some of the DHCP related problems: install a
dhcpcd.exe script that stops/starts FreeS/WAN as appropriate i.e. stop
it on a "down", restart it on a "new" and start it on an "up" if it
isn't running.  This is a heavy-handed approach but it does at least
keep the routing and eroutes consistent and ensure that connections
are re-negotiated on an address change.
