  aptitude's dependency removal has always been intended to be
conservative: it doesn't treat a package as a candidate for removal
unless it actually "saw" it get autoinstalled.

  Apparently there have been bugs in this for years and no-one reported
them until they caused trouble for the d-i team several months ago.
They should be fixed in stable's aptitude now, and I would appreciate
bug reports on any transition problems that remain.
