I wouldn’t say Metroid and Castlevania merging into the name of a new genre label is quite the same as expecting every game with the word “Soul” in the title to be a souls-like.
Rogue has a similar problem sure, but I don’t think it’s at the point of expecting every game using the word to be a Rogue-like. Recent example 40k: Rogue Trader.
Right cause the same thing didn’t happen to Metroivanias and Rougelikes.
Popular use and association will make souls into the next one of them. Directly in the name or not that is the label that’s sticking.
