Plus, this is still a Final Fantasy game. There's expectations and precedent to take into consideration. That's why we have icons like Black Mage, instead of watering things down with stuff like Fire Mage and Frost Mage.
The job with the least precedence so far is Reaper, and even that has design ties to FF Type-0.
We simply can't have as many jobs as we want. Each job needs to justify it's existence.
We could potentially gain Mystic Knight as a tank, there's a series precedent there, but is another tank job justified? Would Mystic Knight as a tank bring anything new the other tanks don't already do? Would it be unique enough? Would it use a unique weapon? Is there a compelling story to tell that could only be told through Mystic Knight job quests? Is there enough demand for a fifth tank? Would it get more people playing tanks? Does that justify stretching the workload further? All of these need sufficient answers.
Another example is a job concept someone keeps posting, a 'Modern Assassin' job that dual wields a pistol and a katana. By all means in some other game it could be a cool job to play, but in the context of FF14 it doesn't tick the boxes, it doesn't quite fit the games aesthetic and it's not using any unique weapons, in fact it's amalgamating bits of three jobs, Machinist, Samurai and Ninja. So in terms of flexing your creative muscles, go for it, but it's not something that's going to make the cut for a new job in FF14.
