Thread for Inovelli Blue?

Does anyone know the current state for re-flashing Inovelli Blue switches to Thread? I haven’t been paying attention the last year so I don’t know if they released that or if it works reliably. I did try looking through the community pages without finding anything definite (plus that might not include any actual experience trying it)

I recently saw a couple new Thread devices, so maybe it’s time to start using that. My entire Zigbee network was intended to be flashable to Thread: all I have is SkyConnect and some Inovelli Blue switches. More importantly, that should be a good foundation for a strong mesh to support other devices (and I don’t have a reason for a strong Zigbee mesh). I know SkyConnect multi-protocol didn’t work out but I believe reflashing to Thread is fine. I know Inovelli Blue can’t be reflashed over the air, but that’s ok. Is there Thread firmware and what are your experiences with it?
