I was watching Fantastic Beasts and where to find them when Lumos shined above my head. It states in FB that if a wizard oppresses their power then it will turn into an obscurial/obscurios. This lead me to think that Hogwarts didnt want Harry to become an obscurios. This is because obscurioses are powerful forces that can cause a lot of havoc, and with Harry being a horcrux and having a part of Voldemort in him then he would be a very, very powerful obscurios.
Is this a reasonable reason? Or did Hogwarts just not want Harry to suffer with the Dursleys?
