The liability is:
- Some users will not have tasksel installed on their system. Telling them
to run aptitude install aptitude tasksel will install a package that they
don't need or want.
- Some users will know that they don't want tasksel installed, and ignore
these instructions. That increases the number of upgrade paths that we
need to support.
- tasksel has dependencies that wouldn't otherwise need to be pulled in at
this early stage -- in particular, a newer version of debconf than shipped
with sarge. This makes the first stage of the upgrade more complex, and
therefore increases the risk of bugs. We want this part of the upgrade to

understanding what happened because of the larger number of packages

So your concern is that users will try to resolve this dist-upgrade
interactively, rather than choosing one of the solutions from the
commandline interface, and that in the process they'll use the task list? I
suppose this is possible, but a) I don't see how the task list is relevant
to resolving a dist-upgrade problem, b) using aptitude interactively is
already not part of the documented, recommended upgrade procedure, right?
