Wrangler types using "fetcher" type for RPC binding rather than Service

I have a binding in my wrangler.toml

services = [
    { binding = "TRACE_EXPORTER_SERVICE", service = "observability-service", entrypoint = "TraceExportService" },
]

services = [
    { binding = "TRACE_EXPORTER_SERVICE", service = "observability-service", entrypoint = "TraceExportService" },
]

However when using

wrangler types

wrangler types

command to generate types I get

TRACE_EXPORTER_SERVICE: Fetcher;

TRACE_EXPORTER_SERVICE: Fetcher;

But I believe it should be

TRACE_EXPORTER_SERVICE: Service<TraceExporterService>;

TRACE_EXPORTER_SERVICE: Service<TraceExporterService>;

Am I wrong here or missing something, or is this not supported yet with wrangler types?
