Not sure about that either. But if it IS implemented, I think those missions don't start showing up until you hit the 150K cap
My transfered character on Tribble, has Rank 4 on every category but Recruitment and Colonial. Despite that, my hightest is somewhere in the 130K range. I haven't seen any of these missions either, probably because I haven't hit the 150K limit.

Been playing STO since Open Beta, and have never regarded anything as worse than 'meh'.
