While Te Aihe is unlikely to be as competitive given the significant developments teams are making to their second generation AC75s, America's Cup historian Tom Ehman says an exemption would infuriate the other challengers and give Stars + Stripes vital insight into where they stand compared to the other three teams – Luna Rossa, American Magic and Ineos Team UK – without having to race them.
"This has never happened before," Ehman told Newshub. "It's outrageous.
"They'll be as mad as hell … Challengers betraying other challengers.
"I'm calling them Stars & Stripes Team NZ."
Team NZ would welcome another challenger, which would be a financial boost for the regatta and Auckland's viaduct.
But getting challengers and the arbitration panel to agree to an exemption will likely be difficult, with Stars + Stripes already missing several previous deadlines.
The US syndicate insist their challenge is still alive and last week released a video teasing their involvement.
