Why don't we have Saw Gerrera and Tactical Droids yet?

People have been asking since 2018 for Saw Gerrera. He seems like a really important character in the overall scheme of things. As he makes more appearances in story and on screen than some popular characters.

I had also wondered if we would ever see some of the other characters from the Clone Wars and Rebels series. The tactical droid leader is in almost every episode with droids. I could see it being a powerful droid support unit. Similar to what Thrawn does for Empire squads and Yoda does for Jedi squads.

I get that these forums are for the community to voice their opinions, but do the devs look at these? It's my first time posting.
