For some definition of "out there", perhaps.  Perhaps not.

The majority of faces should _not_ inherit from such faces, IMO.

Inheritance should be based on similarity (preferably set inclusion) of use
(usage, use case, purpose), not just on similarity of face attributes.

A new face should not inherit from face `region' just because its default
attributes are the same as the default attributes of face `region', for example.
