Unlike the old C* linked at the top of this particular thread, Ada is still seeing active development in its language standard and implementations and new work. Pascal (via FreePascal and Delphi, in particular) is also still maintained and in use today.
Neither of those languages are obscure. If enough time passes that they become considered so, by all means there is no reason to condemn the names to an eternal graveyard.
