The OTLP exporters pull gRPC and protobuf — otlptracehttp as much as otlptracegrpc, since they share otlpconfig. luxfi/trace v1.4.0 exports the ZAP span exporter directly, so each service keeps its own TracerProvider and resource attributes and only the transport changes: a JSON SpanBatch inside a ZAP envelope, read by o11y/pkg/zapreceiver. ZAP takes host:port, so a URL scheme is trimmed rather than passed through — it has no meaning on this wire. otlp is now zero in go.mod.
