You would think so, and so would I, but as usual in security software,
we would be wrong.  There are key management problems in making the
swap partition usable by the BIOS, by subsequently booted copies of
this OS or different OSes, etc:

  "Encrypted swap no longer mounted at bootup"
  https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/953875

  "Reinstalling over a previous installation with encrypted swap displays a "Continue without swap" warning dialog"
  https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1066342

  "encrypted swap reused from previous install when wiping and reinstalling"
  https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1097890

  "Do not offer hibernate with encrypted swap"
  https://bugs.launchpad.net/ubuntu/+source/devicekit-power/+bug/423608

  "gnome-power-manager hibernates even when using encrypted swap"
  https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/722145

Sigh...
