Support for `oneOf` with discriminator

I am looking to create a provider for an API that makes heavy use of [polymorphism](https://swagger.io/docs/specification/data-models/inheritance-and-polymorphism/), i.e. a `oneOf` with a discriminator value. I am aware that [this is currently not supported](https://github.com/hashicorp/terraform-plugin-codegen-openapi/blob/main/DESIGN.md#known-limitations). [This post](https://www.reddit.com/r/Terraform/comments/kl5hjf/polymorphic_resources_provider_best_practices/) has a couple of ideas for how a provider could support polymorphism.

Is support for this type of polymorphism on your roadmap? If yes, do you have thoughts on what the generated spec would look like? If not, do you have thoughts on alternative approaches?
