A way to get the `tfprotov5/6.Schema` from `schema.Schema`

I'm trying to create a (standalone) List Resource, in which case I have to implement the RawV(5|6)Schemas method. Basically, the logic is to new a resource, then call its .Schema() and .IdentitySchema(), and assign these schemas to the response of the method.

However, there isn't an obvious way to convert:

• Resource schema schema.Schema to tfprotov5/6.Schema
• Identity schema identityschema.Schema to tfprotov(5|6).ResourceIdentitySchema

On the other hand, the SDKv2 has those helper methods:

https://github.com/hashicorp/terraform-provider-azurerm/blob/d8bca21ec306ae6cfe48fa906700a4a1967222dc/vendor/github.com/hashicorp/terraform-plugin-sdk/v2/helper/schema/core_schema.go#L404-L417

Does this mean to support List Resource under fw, the only option is to extend the Resource?

Seems my understanding is not correct. If the corresponding resource is implemented by fw, no need to implement the RawV(5|6)Schemas.
