Worked: (newest version of Blender that worked as expected)

Short description of error
Using 'Add Cube' on a 1meter cube, holding shift for unit size, it creates a 2meter cube instead. Note: Origin of the 1m cube is not in the center: on bottom.

Exact steps for others to reproduce the error

Snapping is on
Use 'Add Cube' tool, snap to cover one side on a 1m cube with the origin on the bottom (in the center of the scene) with SHIFT for unit size.
A 2m cube is created instead of expected 1m cube.

Can confirm, it is not only an issue with the add tool, python is also inconsistent, check:

bpy.ops.mesh.primitive_cube_add(size=2, enter_editmode=False, location=(0, -1, 0), rotation=(0, 0, 0), scale=(1, 1, 1))

vs

bpy.ops.mesh.primitive_cube_add(size=2, enter_editmode=False, location=(0, -1, 0), rotation=(0, 0, 0), scale=(0.999, 0.999, 0.999))

Will check.

Size 2 is actually correct here (it is the default for prims in blender), scale is what is handled wrong, there is an exception in 16943c0146 especially for the 1x1x1 scale case.

#77942 is a bit related, looking into making this all consistent now.

Yes, you failed to reproduce the issue ;)
I just verified it in 2.93a as well. Attaching blend file for clarification.
