Do you think these new cosmic beings specifically Lady Death will be actually intertwined in the MCU films or is she a one off character?

Lately it feels as though we are being introduced to these brand new and super cool characters but after about 1 film or tv show they kind of disappear but you can't do that with the literal embodiment of MCU death now that she was introduced...or can you? I feel like now that we have Eternity in the MCU from Thor love and thunder it was honestly about time that they introduced death and I honestly feel like the Living Tribunal is next and we are probably gonna be seeing Galactic soon but what do you do with these all these cosmic guys? Are they just one offs that will be seen once but never again or are they actually characters that we are going to see for a while? Should I get invested into these characters knowing that they might not be seen in the MCU after 1 movie? In my personal opinion I feel as though we should see this character again...she was fun and honestly unexpected(but kinda expected) and my favorite character from the show. It's not lost on me either that Aubrey Plaza might not be acting for a while due to the death for her husband which honestly is so tragic and I pray for her and I cry with her but I just love the character so much.
