The hook itself spontaneously introduces it and uses it. There's nothing
magical about config variable, e.g. it could also be "xyz.abc" instead
of "hooks.allownonascii".

But perhaps it should be documented as the functionality of the default
hook in githooks(5), similarly to how we document
hooks.allowunannotated. Patches welcome :)
