   I like this idea, but I'm not sure how it would work as Pools are read _and updated_ by the Airflow scheduler, whereas configuration, connections and variables from environment variables are read-only.
   
   Maybe we could have something on scheduler start-up which checks for `AIRFLOW__POOL_*` environment variables and creates / updates pool sizes accordingly?
   
   I'd be happy to work on this, but I think I need to understand the requirements better first. Could you expand on which aspects of pool configuration you want to manage via environment variables?
