No, it isn't.

Outline minor mode provides an abstraction that needs to be 
implemented by the major mode in use.

The outline-regexp variable is a large part of that abstraction, 
which is why I've tried to direct your attention to it. If and 
when a major mode sets that to a sensible value, it is providing 
the implementation for outline-minor-mode that would otherwise be 
missing.

Not default. Missing.
