You have got that a bit wrong.

In the event of a MCAS incident or a "runaway stabilizer" the procedure calls for cutting all electricity to the single stabilizer motor. After that there is no longer a thumb switch available.

The pilots then need to trim with the manual wheel which is evidently impossible in some speed and stabilizer position ranges. (On why that is so read my piece.)

The manual trim wheel is not a "left over" but its function is a critical regulation requirement for all 737.

The A-320 has 4 times redundancy for moving critical flight surfaces. The extra margin of safety is clearly on its side.
