There is also the question of inertia. People are used to certain software, and recommend this to others. In many cases I'd rather have a CLI that I know how to use, than a finnicky GUI that I don't.
Yep, also it works, and if it works, why change it?
Also the documentation exists.. find a 10 year old manual how to connect? Still works? Great! A rarity with modern software (and programming languages).
Also, since it's not really "exposed", lack of maintenance doesn't matter a long as it just works.
