The GSR for NWT has a rule allowing F-22s and F-35s to be used as Wild Weasels. This rule is not marked with [NWK]. Is there a gameplay reason this change wasn't carried to this game?
Ummm...no. It can certainly used be there as well. I'm not entirely sure why some were marked and some weren't. It's pretty safe to say that allowing any and all NWT optionals, within reason, in NWK which don't conflict with NWK rules is OK.
