It seems that Team Cherry was not ready for some development scenarios.
Recently, the author of the YouTube channel Kilroy Was Here talked about his adventures in Hollow Knight Silksong. He managed to do a softlock.
He did not release the Bell Beast; instead, he went the other way — he went to the West. Then he farmed resources to purchase the key and opened the locked door.
Soon a section appears where, as it may seem to an ordinary player, it is impossible to pass without a dash, but there is a way out — it is necessary to kill Hornet. After resurrection, a cocoon spawns, which can be used to get to the desired platform.
Then Kilroy Was Here went to the point of getting into prison and faced a problem — since the Bell Beast is still imprisoned, Hornet cannot escape.
