I don't think this has to be a stub, we have NtGetNextThread() in already. Also this is missing corresponding wow64 changes.
I've added the missing wow64 part (initially I only tested 32-bit, now I know that changes like this need 64-bit testing as well).
The app in the linked bug report definitely benefits from the stub. Is it going to hurt something to add a stub before adding a full implementation?

it's not that tricky to add an implementation and a majority of it can be copied over from get_next_thread, so I think it's probably better just to add an implementation now rather than later

If you want to add an implementation, by all means go for it. I was just trying to be nice and address a neglected bug report.
