The century old tradition has set up a couple rakes for native speakers to step into. "Selbständig" (freelancing) is obviously derived like self-standing, but "selb" is archaic and completely unused, prompting native learners to write 'selbstständig, which is wrong. Couple more ones like this. Ask a native speaker about hinüber vs herüber, they will be perplexed, because it feels so dialectal. And nobody even knows about imperfect tense vs perfect tense, it's just stylistics to most.
