[Pkg-samba-maint] Bug#975330: samba: Upgrading python to 3.9 wants to remove samba completely

Package: samba
Severity: important

Dear Maintainer,

Python was updated to 3.9 in unstable a few days ago. However, if I allow apt
to d-u, it will completely remove samba as seen here

The following packages were automatically installed and are no longer required:
  libarchive13 libavahi-client3 libcups2 libjansson4 libldb2 libpython3.8
  libpython3.8-minimal libpython3.8-stdlib libpython3.9 libtalloc2 libtdb1
  libtevent0 libwbclient0 python3-dnspython python3-talloc python3-tdb
  python3.8 python3.8-minimal samba-common tdb-tools
Use 'apt autoremove' to remove them.
The following packages will be REMOVED:
  libsmbclient python3-ldb python3-samba samba samba-common-bin samba-libs
  smbclient
The following NEW packages will be installed:
  libpython3.9 libpython3.9-minimal libpython3.9-stdlib python3.9
  python3.9-minimal
The following packages will be upgraded:
  libpython3-stdlib libtalloc2 libtdb1 python3 python3-minimal python3-talloc
  python3-tdb
7 upgraded, 5 newly installed, 7 to remove and 0 not upgraded.
Need to get 6,922 kB of archives.
After this operation, 45.7 MB disk space will be freed.
Do you want to continue? [Y/n] n
Abort.

What is really odd is that both samba and python were updated to their new
versions the same day, samba on 4.13.x and python on 3.9, but I guess samba
4.13 was built with python 3.8 as a dependency.

p.s. The above are NOT from my MAIN system, which runs debian testing amd64,
but from a secondary one running unstable i386.
