Deprecation and migration
Decision questions
- Does the old system still provide unique value?
- How many consumers? Migration cost each?
- Is replacement production-proven?
- Cost of NOT deprecating (security, maintenance)?
Compulsory vs advisory
| Type | When |
|---|---|
| Advisory | Stable legacy, optional migration |
| Compulsory | Security risk, blocks progress — need tooling + deadline |
Default advisory unless risk justifies force.
