All of them. It means that you can't test and verify that a daemon
works correctly with systemd in Debian and expect it to work the same
with systemd in other distributions.
I'm not saying those kinds of changes are unwanted. I'm saying they
should go upstream and that I am unwilling to carry those patches in the
Debian package.

I think you're just being confused by it giving you some information you
don't need. The documentation in question reads:
Internally, these functions send a single datagram with the state
string as payload to the AF_UNIX socket referenced in the
$NOTIFY_SOCKET environment variable. If the first character of
$NOTIFY_SOCKET is «@», the string is understood as Linux abstract
namespace socket. The datagram is accompanied by the process
credentials of the sending daemon, using SCM_CREDENTIALS.
For details about the algorithms check the liberally licensed
reference implementation sources:
http://cgit.freedesktop.org/systemd/systemd/plain/src/libsystemd-daemon/sd-daemon.c
and
http://cgit.freedesktop.org/systemd/systemd/plain/src/systemd/sd-daemon.h
SCM_CREDENTIALS is generally not something the sender sends, it's
something the receiver sets on the socket using SO_PASSCRED.

It's not.
