ASI-ARCH focuses squarely on creating a workflow/process for optimizing for any goals. If HRM is not involved in ASI-ARCH it is likely that things are currently too nuanced for the LLMs to "daydram" about for LLM tasks. And if we seed the model with HRM, then we have to anticipate them mutating HRM into an un-HRM state. Can you think of any other adjacent papers that has similar ideas of "System-2" and stacked thinking?
