# If you write a node that is so useless that it breaks ComfyUI it will be featured in this exclusive list

# "native" block swap nodes are placebo at best and break the ComfyUI memory management system.
# They are also considered harmful because instead of users reporting issues with the built in
# memory management they install these stupid nodes and complain even harder. Now it completely
# breaks with some of the new ComfyUI memory optimizations so I have made the decision to NOP it
# out of all workflows.
