I used to work on a monolithic Rails app and migrations would build up over time. We'd "collapse" migrations by doing a schema dump every couple weeks. Without it, they'd accumulate thousands of migrations which would take quite a while locally and in CI to rebuild the database It's also much easier to programmatically inspect. In ActiveRecord, the model attributes are dynamically determined from the DB (for better or worse) so you need to also take any migrations into account to know what fields a model has. From an inspection standpoint, it's nice to have the desired representation in code
