I was about to bump dhcpcd-base as ifupdown dependency, but... if isc-client-dhcp is a Recommends, is because not all users want a dhcp client installed, where all the ipv4 is handled statically, and ipv6 is done via SLAAC. As a user, I don't want/need to pull in dhcpcd-base the next upgrade. So I'd prefer to go forward with the steps proposed by Simon, and s/isc-dhcp-client/dhcpcd-base in ifupdown's Recommends: Unless there is a strong objection, I'll file the override bug report.
