It sounds like you are tightly coupling to implementation and also expecting this to be the rightfully maligned ESB. Airflow, aws step functions, etc are complex event processors and shouldn't typically be used as wide as you are suggesting. It is a common pitfall to accidentally build distributed monoliths, and in fact often requires active architectural governance to avoid it. Airflow isn't perfect, but I highly recommend considering a review on why modernization efforts fail. The what and the how shouldn't be tightly coupled, especially across capabilities. But yes. Airflow makes a poor ESB/DTC, but that is not the target for the project.
