We want to remove one of the remaining big pain points of Introspection: If you manually adjusted your data model after introspection (to rename fields or models, or add default IDs for example) these changes are currently lost once you introspect again ("re-introspect", for example, because your database was changed manually or migrated by another tool).

This project consists of many individual problems that we are tackling one by one:

• [Re-Introspection] Keep manual changes to relation field names #2503: Keep manual changes to relation field names
• [Re-Introspection] Keep @map and @@map  #2545: Keep @map and @@map
• [Re-Introspection] Keep defaults that are not persisted in the database (cuid() and uuid()) #2534: Keep defaults that are not persisted in the database
• [Re-Introspection] Keep order of models of existing Prisma schema #1997: Keep order of models of existing Prisma schema
• [Re-Introspection] Keep order of fields of existing Prisma schema #2968: Keep order of fields of existing Prisma schema
• [Re-Introspection] Comments in the schema are removed by re-introspection #3052: Keep comments in schema
• [Re-Introspection] Keep @updatedAt #3335: Keep @updatedAt

We might also decide that some of them are not worth the effort.
