It’s not a common use-case but I could see it being useful for sharing hardware that requires exclusive access like GPUs/ML accelerators.

Currently if you need GPUs they come with the instance itself meaning you need to boot your VM from scratch, do the work and then shut it down to relinquish the GPU.

With hot-plug you could have continuously running VMs that only attach/detach GPUs as needed, no longer taking the overhead of a full cold boot/shutdown every time.
