Async SPI bus not instatiable on Pi Pico (embassy-rs)

[arminveres]

Hello there, when trying to use a shared SPI bus, which is async, the SdCard cannot be instantiated, since the trait is not implemented. Is there a specific technical reason for this, or was this just not yet implemented?
As you may gather, I am trying to complement this with the oled_async crate, since i need a driver for SH1107

the trait `embedded_hal::spi::SpiDevice` is not implemented for `embassy_embedded_hal::shared_bus::asynch::spi::SpiDevice<'_, NoopRawMutex, embassy_rp::spi::Spi<'static, SPI0, embassy_rp::spi::Async>, Output<'_>>`

main.rs (other initializations for i2c and oled left out):

type Spi0Bus = Mutex<NoopRawMutex, Spi<'static, SPI0, spi::Async>>;

#[embassy_executor::main]
async fn main(spawner: Spawner) {
    info!("Starting main!");
    embassy_rp::pac::SIO.spinlock(31).write_value(1);
    let p = embassy_rp::init(Default::default());

    // SPI clock needs to be running at <= 400kHz during initialization
    let mut spi_config = spi::Config::default();
    spi_config.frequency = 400_000;

    let spi = Spi::new(
        p.SPI0, p.PIN_2, p.PIN_3, p.PIN_4, p.DMA_CH0, p.DMA_CH1, spi_config,
    );
    static SPI_BUS: StaticCell<Spi0Bus> = StaticCell::new();
    let spi_bus = SPI_BUS.init(Mutex::new(spi));

    let cs = Output::new(p.PIN_5, Level::High);
    let spi_dev = SpiDevice::new(&spi_bus, cs);
    let sdcard = SdCard::new(spi_dev, embassy_time::Delay);
}

There is no async support in this crate at this time. See #50 and #154
