I agree. The current style has been default in this many years. Enough time to be got familiar with.

The issue https://github.com/llvm/llvm-project/issues/98559 can also be regarded as the inaccuracy of the manual. That says

Only changing this part may be better.

If the precise alignment is desired, adding a new `AlignOperands` option is the way.
