The telemetry is literally the only way to relate to what is going on aboard the boats. Show us the accumulator % on every rounding, show us true and apparent windspeeds all the time, show us VMG all the time, show us distance to mark, maybe foil trim angles if that information is accessible, or mainsail car position.
The boats are spectacular but I'm sorry to say that the information interface is really lacking.

Take a look at F1 which shows not only speed but position on the track, pedal position, gear selection, DRS deployment/regeneration and more. It's so hard to relate to these boats otherwise; it was fine in the IACC days because the spectacle of everything going on aboard was more than enough to keep the audience entertained, but that aspect is gone these days and needs to be replaced with something.
