They were on T'Kuvma's list.Were we given the date of first contact between the Vulcans and the Klingon Empire? Burnham said that the Vulcans had to fire on a Klingon ship in the year 2016, thus setting the standard for contact between the two peoples for the next 240 years. This begrudging respect between Vulcans and Klingons would seem to be in play in ENT when the former agree to serve as the go-between to return Klaang to Qo'noS after he crash lands on Earth. They clearly have a more stable relationship with the Empire than humans and that seems to carry over into the era of the Federation.
