is there any point of polishing without removing the anodising
No. You can polish to remove anodising, but your basic surface finish is fixed at the anodising stage and you won't get shinier until you've abraded the oxide layer off and are back to bare metal. Bare aluminium alloy doesn't look pretty for long when exposed to cycling anyway.
