Downgrading EVP_PKEYs from containing provider side internal keys to containing legacy keys demands support in the EVP_PKEY_ASN1_METHOD. This became a bit elaborate because the code would be almost exactly the same as the import functions int EVP_KEYMGMT. Therefore, we end up moving most of the code to common backend support files that can be used both by legacy backend code and by our providers.
