@RestClientTest with RestClient (NOT RestTemplate)

I understand the @TestRestClient helps us easily test classes that use RestTemplate to call REST services. I have several classes which use Spring's RestClient (NOT RestTemplate, NOT WebClient) to make REST calls. Can I test such classes with the @TestRestClient or do I need to use something like WireMock? My web searches have drawn a blank.

If not, is such support planned for a future release of Spring Boot?
