They aren't Emacs editing paradigms.  Control-W is a tty driver
editing character.  Nothing emacs about it at all.  (In Emacs C-w
actually does something different.)

  $ stty -a | grep werase
  werase = ^W; ...

Dates back to the beginning of time before command line editing using
either emacs or vi modes existed.

The up arrow is the ESC k here.  There is an escape in the up arrow
terminal sequence (ESC O A on my terminal).  After hitting up arrow
you are in command mode.

Your description was okay.  I confirm that something has changed in
recent versions of bash.

On my Debian system with bash 4.3.30 this works as you want.  The ^W
character anywhere on the line will erase the previous word.  In more
recent bash 4.4.12 it now behaves differently as you are describing
and only deletes the previous word if at the end of the line.
Definitely a behavior change between the bash versions.
