# Which Problems Are Solved
Stabilize the optimized introspection code and cleanup unused code.
# How the Problems Are Solved
- `oidc_legacy_introspection` feature flag is removed and reserved.
- `OPStorage` which are no longer needed have their bodies removed.
- The method definitions need to remain in place so the interface
remains implemented.
- A panic is thrown in case any such method is still called
# Additional Changes
- A number of `OPStorage` methods related to token creation were already
unused. These are also cleaned up.
# Additional Context
- Closes#10027
- #7822
