Very cool. I'll reach out.

When Nick Schrock created dagster, he argued that many "data cleaning" tasks which people attribute to "data engineering" aren't actually "cleaning", but are architecture problems. I believe schema changes also fall into this category. I'm extremely new to data engineering, but when I think about "What are the things which will break this system?" an application engineer thinking "I'm going to rename this column and my tests pass, so this should be fine" will break things all the time. (Similar goes for dropping a column, changing a one-to-many into a many-to-many)
