The most obvious use case I can see for it is SR, however we can already to do this with multi-topology IS-IS. I guess you could do it with MI-IS-IS too. Do you really need multi instance? If not it sounds like you can use MT-IS-IS instead which does work in IOS-XR and Junos. We have lab testeed MT-IS-IS with SR and "it works" in IOS-XR. It's in a bleeding edge Junos image so I haven't had a chance to test it in Junos yet or do iner-op testing. Cheers, James.
