IMHO, post-COVID-19 US carriers will change their tune on the ME3 and pursue adding them to existing trans-Atlantic joint ventures. AA had made its intentions clear by announcing SEA-DOH and strongly indicating other USA-DOH AA flights will later follow. UA needs to beat DL to the punch by bringing Emirates into the fold. UA, for its part, could run EWR-DXB, SFO-DXB, ORD-DXB, and IAD-DXB flights to support such a move.
