I'm not even sure if there is a language which allows demoting
visibility of inherited class members. It would seem odd to me. Just
my 2c, of course. ;-)
C++, C#, VB.Net are three I know of.

So it's possible but discouraged, and they give warnings (and
sometimes errors) for it with the recommendation "Do not exclude a
warning from this rule."
As far as I understand the text on that page, the only case where
it's considered "safe" is if the the method/class is declared
"final". We do not have final methods/classes in Object Pascal, and
such final methods/classes are often considered a cause of problems
in themselves (because you can bet sooner or latter someone will have
some need to override/inherit anyway).
