We already have class methods in RB - only they are called "shared

I agree that pure virtual methods would be nice. It only makes
sense to add
such a feature if RB then enforces that any subclass MUST implement
that
method. ( although in many cases almost similar results could be
achieved
via interfaces or events).
A method that does nothing but call an event does the very same thing
as a pure virtual method, as far as I can tell. The only difference
is that the event does not require one to supply a nontrivial
implementation.
