I'm not disputing your use case for "mca_base_env_list". I'm only lamenting the crapification of our mpirun user interface. We had an earlier change along these lines based on similar reasoning: the easy-to-use-and-remember "--pernode N" was replaced with "--map-by ppr:N:node", which I cannot ever seem to remember.
