Hey @justinretzolk
Do you think this can be prioritised for review?
Since AWS is going to start doing Maintenance on MWAA?

After July 9, 2025, Managed Workflows for Apache Airflow (MWAA) will start updating environments automatically during its weekly maintenance window to ensure that customers are running the latest and most secure code for their particular Airflow version. MWAA has recently released a graceful update feature that will wait for ongoing workflow tasks to complete before removing older workers. However, enabling graceful updates requires an initial, disruptive update. As such, we recommend you to update your MWAA environment at the earliest convenient time before July 9, 2025, to prevent task disruption during the first maintenance window environment update [1]. No changes to your current environment configuration are required.

Seems like we all need to switch to OpenTofu like yesterday
