No … lol … but just like a transmission-located speedo sensor can be easy or difficult to replace depending on the design, so could a transmission-located wheel speed sensor. I think one practical problem with sensing wheel rpm at the transmission is the outer CV joint during turns, might not be exactly the same comparing wheel speed at transmission end vs at wheel.
Think about that for a minute…
You done or still thinking about it? lol
The CV axle does not rotate at a different rpm from one end to the other, what ever the inner joint rpm is the outer joint rpm will be, it is not a torque multiplier or a differential … So what ever the side gear in the diff (differential) part of the transaxle (a transmission with a diff in it such as your Corolla has) is spinning the cv axle assembly that is attached to the drive hub (however it is designed) that in the end the wheel bolts to, they are all spinning the same rpm… The difference is in the spider gears that allow the diff gears to rotate the cv axles, wheels etc at different speeds from one side to the other…
So mounting the abs sensors are not going to give a different reading given the same diameter of the reluctor wheel or tone ring to the axle, wheel bearing, or diff gear, they are all spinning at the same rpm…

Maybe I shouldn’t think about it … This is what happens when I do my own thinking! … lol … of course you are correct, both parts of a CV joint must spin (inner or outer) at the same rpm.
