Listen I love Jon Snow (a lot), but as long as he's Jon Snow, all of the noble houses of the North are his vassals since they chose and supported him, including House Stark (which is currently Sansa, unless the show officially declare him lord of House Stark and Winterfell). The only reason House Stark is technically royal: his heir(s) is a Stark.

The line of succession is still relevant because all of those lords and ladies inherited their names and positions, the same way Sansa inherited Winterfell.

Another point, Jon was proclaimed King to unite the houses of the North and win the coming wars. Once that is done everything will be forever changed and back to their normal pre-WarofFiveKings, meaning Jon Snow is going to retire and Sansa or Bran will continue the Stark line and name, regardless if Jon survives and if they live. Pros of Jon being King and a Snow: he doesn't have the weight of an entire family on his shoulders, he can act as a free agent politically; meaning he can marry and ally himself without compromising House Stark, and if he dies an entire family won't die along with him (Which almost happened with Robb, luckily his siblings were smart enough to know how to survive.)
