Oh wow - yeah.  For buster-gcc-ibt (which is already slim), we're getting:

Suggested packages:
  binutils-doc bison-doc bzip2-doc cpp-doc gcc-8-locales dbus-user-session
  libpam-systemd pinentry-gnome3 tor debian-keyring flex-doc g++-multilib
  g++-8-multilib gcc-8-doc libstdc++6-8-dbg autoconf automake libtool gdb
  gcc-doc libgcc1-dbg libgomp1-dbg libitm1-dbg libatomic1-dbg libasan5-dbg
  liblsan0-dbg libtsan0-dbg libubsan1-dbg libmpx2-dbg libquadmath0-dbg

  diffutils-doc perl-doc libterm-readline-gnu-perl
  | libterm-readline-perl-perl libb-debug-perl liblocale-codes-perl
  pinentry-doc readline-doc


which is a whole bunch of junk we absolutely do not need.
