My experience with Prisma, which has a very similar DSL for defining schemas, has changed my mind on this. Makes me much more productive when maintaining large schemas. I can make a one line change in the schema file and instantly have types, models, and up/down migrations generated and applied, and can be guaranteed correct. No issues with schema drift between different environments or type differences in my code vs db.

Prisma is popular enough it also has LSP and syntax highlighting widely available. For simple DSL this is actually very easy build. Excited to have something similar in Rust ecosystem.
