That's not how it works.  After the shell writes a command prompt,
it is in insert mode, so you just type a command as normal.  To edit
the current command, or search the history, you type ESC to get out
of insert mode and then perform the edit or search just like in vi
(except that RETURN executes the edited command instead of moving to
the next "line").

It became an IEEE standard in 1992 (and ISO in 1993) for
POSIX-conforming shells, and has remained standard to this day.
IEEE chose not to include emacs mode, so effectively it is emacs
mode that was treated as obsolete (in 1992).
