Sounds so I almost have to feel shame for securing my boxes no matter what
job vendor did ;-)

Just a simple example: I have at least 3 classes of boxes configured
ultimately different and having very different level of
security/fortification. Do you seriously suggest that system vendor will
ship all three level of security configurations? Do you seriously think
that needing quite high level of security for some box I will not go over
all settings influencing it myself? Will you not? We are not Windows
admins, we rely on what we configure or check ourselves. And we do take
security seriously, so, we do go over everything whether the system vendor
does or does not claim they have done that part already (and and claim
they did it better than I can do it). If you prefer to delegate what you
are responsible for (security of your box) totally to someone else (even
as good guys as system vendor is), then I don't know what to tell you.
Yet, I'm sure, majority Unix sysadmins will still do what I do: go over
everything themselves. No matter what someone says.
