One interesting thing is that many reactions actually have to occur in their own compartment- and since we have not lost the mtDNA, it may suggest that having an additional control center is beneficial.there are some interesting theories about the relations of that to lifespan https://www.cuimc.columbia.edu/news/mitochondria-are-flingin....

Couldn't it be that we haven't fully lost mtDNA because it's simply a very slow process that has not yet run its course?
Given how old mitochondria are it seems more likely that its more efficient to have its own DNA.
DNA isn't just abstract information, it's also where the first step of protein / enzyme construction occurs. DNA location matters.
