For example, consider an Org table like
| *This* | is | some text |
| more | | text |
It looks aligned in Org buffers ("*" is invisible), but not when copied
to message buffer.

Sure, but how can an application, say, disable all the effects of visual
representation without (1) searching and let-binding each specific
toggle (and possibly adding more in future versions of Emacs); (2)
re-implementing the existing indentation code (like what
`org-current-text-column' does)?

It would help to list what contributes to indentation/columns in the
documentation.

A toggle: disable all visual contributors.
