I tested the proposed apt with some package installs (not upgrades) that involve lots of dependencies (network-manager), conflicts (upstart-sysv vs. systemd-sysv), and cross-architecture dependencies (ubuntu-emulator:amd64 depends on ubuntu-emulator-runtime:i386). These all work fine.
Given that this breaks upgrades pretty hard and 16.04's release is imminent, I'll expedite the usual 7 day waiting period and release these now.
