I think some are getting used actually, particularly COBOL. I think Modula-2 still gets used in some embedded contexts. But these languages are not exactly pushing the state-of-the-art.
Algol 68 is interesting. It is for sure just for academic and academic enthusiast purposes. Historical and educational value only as you say.
I would guess those languages are added for preservation and compatibility reasons, and it’s also an important thing
