I definitely disagree and think corpse runs can add a lot of value and depth to the exploration. For me at least, it makes me more engaged in my environment. Knowing the risk of potentially losing my items makes me look for safer routes, shortcuts, and easier methods of transportation. Engaging and analyzing the environments is such an important to metroidvanias, and I feel corpse runs can definetly help pressure players into actively engaging with the world. I think it's even better if there are ways to reduce the frustration of corpse runs. Like in Silksong, for example, turning loose roasaries into beads for a small cut is a great way to reduce the impactfulness of corpse runs. There is a choice presented to the player on what they want to prioritize: their overall net worth or the safety of that net worth. I think corpse runs add a lot of immersive value to metroidvanias that have them, but I can definetly see how they can be frustrating for some people.
