I've already got something similar to 2x Ekar with my 46/30 grx cranks, 10-44 cassette and Force AXS electronic shifting, with extended range RD cages. There's enough wrap capacity for the 46/44, but I'll never use it on purpose. I have used it accidentally a few times.
I've got a new 12 speed grx 46/30 crank on one bike but haven't had it out on the road yet. Maybe tomorrow if the roads dry out.
$128 for the 12 speed crank is really cheap.
