I know but doing so was kind of the point.

The views are created by a "database owner" role having
access to all tables. Therefore, roles using the views would
normally gain access to tables they are otherwise not
allowed to read. Hence setting security to invoker made a
lot of sense at first sight ...

Perhaps I am misunderstanding the intent of the feature.
