That will, of course, work. However, I feel that it will only solve this
exact problem, but nothing more.

Just in Org mode, we also need special handling of
`move-beginning-of-line' and `move-end-of-line' for visual mode (for the
same reasons). Does it mean that we need to introduce yet more
"*-function" variables? It will not be scalable.

What I was thinking about is some way for command remapping to:

1. remap overriding minor modes
2. be able to access commands (possible remapped) that are shadowed by
   current remapping

Maybe what I want is advice flexibility for keymaps. (not sure)
