Once we have support for JsonSerializerContext, the discriminators should not cause trim or AOT warnings.
We can't currently use all of the built-in polymorphism support because it has requirements that don't match with our needs. Namely:
The discriminator must be the first attribute in the object being deserialized.
The discriminator must not be included as a property on the POCO
Multiple discriminator values can't share the same POCO type
Modifications
Use the JsonPolymorphic and JsonDerivedType attributes to ensure any generated JsonSerializerContext always includes the derived types in the metadata.
