This question is more likely to get an answer on Super User.
These closure reasons now sound indistinguishable from the migration path A community-specific reason -> This question belongs on another site in the Stack Exchange network -> belongs on superuser.com. It just says that this question belongs elsewhere. The old closure text indicated that the question could be re-asked thus might not fit in its current form.
I find that it's now misleading as it sounds like the question could be copy pasted or maybe should just be moved. Yet, the reason to pick this closure reason rather than the migration path is because the question most likely wouldn't be a good fit in its current form on Super User. It can be posted again but following the standards of the other site.

This question is more likely to get an answer on Server Fault.
Same thing but there is no migration path to Server Fault. Yet this closure reason sounds like one.
I don't know what guidance would question authors be given if their post is closed using one of the above two reasons but it must emphasise that if re-asking on another stack, they should check the help centre and make sure the question fits.
Other than the guidance to authors, the guidance to close voters can be misleading. I assume that the closure reason is the same as before but I really cannot say - maybe there was a change in how this works? Even if there wasn't a change then, how is somebody who sees this dialog for the first time to understand what the difference between these close reasons and the migrations is?
