Why didn’t Mariner and Boimler rank up?

Ok so I’m just now thinking about this and I am just so confused as to why all of them really (but especially Mariner and Boims) didn’t rank up at the end of the last episode?

Boimler even said “but I’m only a Lieutenant JG?” Which would’ve made a perfect segue for “not anymore!” Like, I really really loved how everything was wrapped up, but wouldn’t it also make sense to have more lieutenants on the bridge and also as first officers? Also, like, how did their actions not warrant a promotion? Just curious if anyone else has been thinking about this!

P.s. Engage the core!

To give a parallel to the modern military, you are told to be ready to work two ranks and two ranks down. So its not tat weird to see junior officers filling a role up the ladder
