Not unless something actually Breaks: or Conflicts: or the user runs
autoremove.

If a leaf package bar changes from Depends: python-foo to python3-foo,
then python-foo will remain installed. There are lots of packages in
Stretch that are not in Buster. Upgrading leaves them in place unless
there is something which actively Conflicts: or Breaks: them. That's
why autoremove is so useful after dist-upgrade.
