SpiceDB newbie and very old developer here. I think I want to manage the spicedb schema as a list of version tagged .up/.down schema migrations, similar to modern SQL schema migration tools. We mostly want this so that we can: 1. flash dev instances up to the latest schema 2. improve feature flag management that depends on schema changes 3. monitor and log schema migration workflows (db backup before migration, etc.) I don't see support for this so I'll have to make my own schema_migration table, workflows, etc. This lack of support raises some fundamental questions: What are others doing to safely automate/manage schema migrations? Are these so infrequent that people are comfortable doing two stage (non-breaking change) or four stage (breaking change) migrations manually?
