But it's not symmetric!

Official SRS

Tetris Worlds and Tetris DS are based on the Tetris Guideline, including SRS. They have the following behavior:

iiii

Rotated left

Soft dropped

Rotated right

But the wall kicks are not symmetric, as TW and TDS prefer to kick up rather than down when rotating left:

iiii

However, an extra block impedes the choice of the upward kick position:
