Subject: [PATCH] feat: temporarily disable compatibility mode

- Add DISABLE_COMPATIBLE macro to disable compatibility mode features
- Mark CompatibleBackend class with deprecation warning
- Simplify compatibility check functions to return false when disabled
- Retain original code for potential future re-enablement

Note: Changes are temporary, module may be re-enabled in future releases.

Log: Temporarily disable compatibility mode.
