First you say, the distro, and now, it's the developer. So the reason is
political, not technical ("postfix" developers don't provide systemd
files so RedHat will have to).

It's more complicated than that.

What if the command pathname contains a space character?

<URL: http://www.freedesktop.org/software/systemd/man/systemd.servic
e.html> states:

  The command to execute must an absolute path name. It may contain
  spaces, but control characters are not allowed.

So how does one express whitespace? Quotes are not allowed in the
command name because the first character must be a slash (/).

Furthermore, the rest of the arguments are quoted in a complex, yet
barely documented manner. I ended up enclosing the startup logic in a
bash script and invoking that script from the .service file.

We concluded as much: /usr/lib/systemd/system. The man page advises to
consult pkg-config, but pkg-config might not be available on the target
machine, IIRC.

As a developer, I don't have that privilege. I have to do the "right
thing" for the user, who could depend on systemd and selinux.
