#1932 introduced heuristics to discover and preserve serialized types, for backwards compatibility in xamarin scenarios. The heuristics give no correctness guarantees and will not prevent warnings when using reflection-based serializers (but the xamarin SDK turns off trim warnings globally).

dotnet/runtime#72910 tracks porting this logic to NativeAot for parity with the linker. Could we instead turn off the serialization discovery (maybe with <TrimMode>full</TrimMode>) by default, and only use it for the xamarin scenarios?
