LGTM. Since we're removing the BetaApi annotation from the HttpJsonServiceStub and I don't think the GrpcServiceStub has an BetaApi annotations, can you check if we still need BetaApi in the FIXED_TYPESTORE?

sdk-platform-java/gapic-generator-java/src/main/java/com/google/api/generator/gapic/composer/common/AbstractTransportServiceStubClassComposer.java

BetaApi.class,

If neither transport needs it, I think we can remove it.

I think the annotation is still used in

sdk-platform-java/gapic-generator-java/src/main/java/com/google/api/generator/gapic/composer/common/AbstractTransportServiceStubClassComposer.java

Lines 518 to 520 in b28235a

	if (!PackageChecker.isGaApi(service.pakkage())) {
	annotations.add(AnnotationNode.withType(FIXED_TYPESTORE.get("BetaApi")));
	}
