The only concern I would raise is there some expectation for latency of
hotplug? 300ms doesn't seem like it would irk the user -- it won't be
noticeable unless using a kvm or equivalent. I would be more concerned
if there was a line in the conformance tests that expect a response to a
hotplug interrupt within a certain time window.
