Right from that file listed above:
| If you do the above your package does not need to call ldconfig in its
| maintainer scripts. It is especially important not to call ldconfig in
| the postrm or preinst scripts in the case where the package is being
| upgraded (see Details of unpack phase of installation or upgrade,

| library links point to them, just before dpkg continues the
| installation and removes the links!

I think you're (a bit) unduly alarmed. From my interpretation, it's
not a bug to call `ldconfig' from postinst, it just shouldn't be
necessary. So why do it if it doesn't have to be done?
It may be a bug if the package doesn't include the .so file in the
actual package as described in the Packaging manual. However, the
packaging manual says "should" and not "must", although I remember
reading on the Policy list that where it says "should" it really
should say "must". Nor am I sure whether the Packaging manual
carries the weight of law like the Packaging manual does.
Anyhow, what I would do is certainly file bugs against packages which
seem to create the ldconfig error messages which you originally cited,
since that really is the harmful behavior (confusing, scary messages
during postinst) which really does lower the touchy, feely,
friendly-factor of Debian.
