Being a team leader does not automatically make one the focus of a story. Cyclops is the leader of the X-Men, yet in the original animated series, the main character was Jubilee. Later, Wolverine took over the show. Ruby and Jaune being team leaders and main focus characters is coincidental at best. Cardin hasn't been a focus except in his torment of Jaune. Sun hasn't been a focus except for one conversation with Neptune. Of course, the show is still in its infancy. Teams CRDL, SSSN, and CFVY have yet to see any real focus.

The point is that even if the show flashes back to stories about Team TRQS, Taiyang is not the guaranteed focus. As a matter of fact, the only reason to flash back at all would be to clarify Summer's story and that can be accomplished either by using the perspectives of the three survivors as outside witnesses or via Summer's firsthand account of her experiences as part of the team (maybe left in a letter to Ruby).
