  | Posix doesn't make that distinction.

Actually, it does,

        Input Mode Commands in vi

        In text input mode, the current line shall consist of zero or more
        of the following categories, plus the terminating <newline>:

            1, Characters preceding the text input entry point

               Characters in this category shall not be modified during text
               input mode.

            2. [...]

In vi, input mode is used to input data.  That's it.   The only editing
that is supposed to be available is that which you would have when typing
using the regular tty driver input correction abilities, which apply only
to making changes on characters typed since the last \n - and only to erasing
backwards.
