I have strongly mixed feelings about installing intel-microcode by default.
Of course it's good to have the latest microcode bugfixes.
What worries me is that Intel provides no release notes at all.
They didn't even put up a warning for the update that disables the TSX instruction.
Removing an instruction while processes are already running is of course highly problematic, see bug #1370352.

Title:
  intel-microcode should be installed by default, when the CPU is
  GenuineIntel

Status in intel:
  New
Status in ubuntu-drivers-common package in Ubuntu:
  In Progress
Status in ubuntu-meta package in Ubuntu:
  In Progress

Bug description:
  intel-microcode should be installed by default on the bare-metal
  systems which are running on GenuineIntel CPUs, by the installers.

  Similarly other microcode packages for other CPUs brands should be
  considered for inclusion (e.g. amd64-microcode).

  I hope that ubuntu-drivers-common can gain ability to detect cpu
  series and/or vendors, packages that provide microcodes similarly
  declare support for cpu series and/or vendors, the microcode packages
  are shipped on the CDs in the pool directory, and installed on to the
  target machines as part of the installation.

  This should help with rapid correction of bugs and behaviour of the
  CPUs in the field.
