I don't care what security bible is quoted. Just because this document says
that "Availability" is a component of "Information Security" doesn't mean
that every action which improves availability is a security measure. To
stand behind such a simple-minded interpretation is ridiculous.
An action which prevents a potential attacker from crashing the system
improves availability in a security context.
An action which makes the system more stable or maintainable might also
improve availability, but has nothing to do with security.
Can we wrap this up now? It's getting very, very stupid.

Academics, certification companies and other such entities often have
difficulty relating to actual practice. But in this case, I think it's more
likely that you are misinterpreting the text.
