This is probably more efficient in high dimensions. I am thinking mostly
about 1,2, and 3. I have many routines and
want to avoid keeping three versions of each in sync. Your method will
perform worse in 1D, and maybe 2D and 3D too.
But, I'm starting to think that, for most of my applications,

Oh yeah, or x[direction] += rand(-1:2:1) to avoid the need for the
allocation in the first place.

You could even do x[direction] += rand([-1, 1]). The allocation can be
avoided by defining a global constant with [-1, 1] as its contents.

You can also do "if rand(Bool)"
