I'm not.

This depends a lot on which Debian release you build the package and
what version /usr/bin/python3 has on that system as those versioned
dependencies are calculated at build time.
So if you build that package on Debian Stretch where python3 is 3.5.3,
the above is true, expected and wanted: the package has a dependency
on python3 << 3.6.
And if you build it on Debian Unstable now (where python3 is currently
3.6.4), it's expected and wanted that the package has a dependency on
python3 << 3.7.
Short said: It's built to work with the currently installed version of
python3 and _no_ other (earlier or later) version. That's why Debian
rebuilds such packages when a new python3 minor version enters Debian
Unstable by doing binNMUs.
So there is no bug at all and everything works as expected and wanted.

Of course! Because it's no binNMU if you just build it from source
without the appropriate commandline options for a binNMU.
Please first read
* https://wiki.debian.org/binNMU
* https://www.debian.org/doc/manuals/developers-reference/pkgs.html#binary-only-nmu,
* the dpkg-buildpackage(1) and dpkg-genchanges(1) man pages on the
options -B, -C, -e (both) -V and -D (dpkg-genchanges only)
* the deb-substvars(5) man page section on the topic "binary:Version"
* and the dh_python3(1) man page
before writing any further replies to this thread. Thanks.

I talked about "source packages" (not "sources") which is a very
precise term in Debian context: A Debian source package means a .dsc
file including all files referenced in there (usually a .orig.tar.gz
and a .debian.tar.xz file).

The we disagree, because a debian folder of course is part of every
Debian source package.
