Yes, but we're working on a converter from DDL sql to pgroll json.
The reason for JSON is because the pgroll migrations are "higher level". For example, let's say that you are adding a new unique column that should infer its data from an existing column (e.g. split `name` into `first_name` and `last_name`). The pgroll migration contains not only the info that new columns are added, but also about how to backfill the data.
The sql2pgroll converter is creating the higher level migration files, but leaves placeholder for the "up" / "down" data migrations.
I completely understand the need for a higher-level language above SQL, but straight JSON is a deal-breaker. It's not just comments, it's also that editors won't understand that JSON should have syntax-highlighting to help people catch trivial typos. A configuration language that allows for importing a file as a string would allow users to write the SQL in files with .sql extensions and get syntax-highlighting.
pgroll is written in Go, so if you were to accept configuration written in CUE, you would get the best of all worlds:
