This stems from lsb_release switching to reading the cross-distro
standard file, /usr/lib/os-release:

| $ cat /etc/debian_version
| 10.1
| $ cat /usr/lib/os-release
| PRETTY_NAME="Debian GNU/Linux 10 (buster)"
| NAME="Debian GNU/Linux"
| VERSION_ID="10"
| VERSION="10 (buster)"

So arguably base-files should be updating that file with point release
information, just as /etc/debian_version is. The spec [1] does not rule
that out, and other distributions do so:

| $ cat /etc/os-release
| NAME="Red Hat Enterprise Linux Server"
| VERSION="7.7 (Maipo)"
| VERSION_ID="7.7"
| PRETTY_NAME="Red Hat Enterprise Linux"

Please consider doing this urgently in stable, and possible even as a
stable update - it's having knock-on effects for us in several places
already, and I'm sure there will be other users with similar stories.

Severity upgraded because it causes an unexpected behaviour change in
lsb_release, but feel free to adjust.
