bug 1173728 is about programmable completion being loaded by default, or
not.  Further discussion about how and whether it is should go there.
Sorry for the tangent about it in this bug.

Title:
  Bash-completion slows up the start of bash

Status in bash-completion package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: bash-completion

  I have been noticing that bash has unusually slow start-up times.
  After looking into the problem, I found out this is mostly caused by
  the execution of /etc/bash_completion (calls to this exist in several
  places). Of course, removing them speeds up the start but leaves a
  less functional shell. As a work-around I would like to suggest
  starting up /etc/bash_completion in the background. In this way, bash
  will start quickly, have access only to basic built-in completions for
  the first 2 seconds until /etc/bash_completion finishes executing.
