Having the ability to run multiple VMs is one of the major pluses for unraid. but with not enough slots on the motherboard for having a multiple usb cards for passthrough or finer control of bluetooth devices.  Having the some more finer iommu group control so that users can use wider variety of pcie multi cards. like whats discussed in this forum post or using pcie expansion systems like this https://www.onestopsystems.com/product/µcube3-metal-expansion-enclosure-5-pcie-x4-slots .

 

 

I don't quite get what the request is? 

I think they want unRaid to do more of the things.
