True, it was made the default when CONFIG_SECURITY=n a few years ago,
and switching it off when toggling CONFIG_SECURITY is probably unsafe
for unsuspecting users/testers.

Subject: [PATCH 1/1] security: compile capabilities by default

Capabilities have long been the default when CONFIG_SECURITY=n,
and its help text suggests turning it on when CONFIG_SECURITY=y.
But it is set to default n.

Default it to y instead.
