bug#37447: 26.3; Commands on <delete> and <backspace>

[Sebastian Urban]

C-h c M-<delete>:
    M-DEL (translated from <M-delete>) runs the command
    backward-kill-word

C-h c <delete>:
    <deletechar> (translated from <delete>) runs the command
    delete-forward-char

C-h c C-<delete>:
    <C-delete> runs the command kill-word

I'm not sure how this could help me or how I'm suppose to understand
this.

M-<delete> doesn't run command, but is translated to 'M-DEL' that does
run the command.  M-<backspace> uses the same translation.  Couldn't
it be:
- <M-delete> runs the command kill-word
- M-DEL (translated from <C-delete>) runs the command
  backward-kill-word

Or couldn't 'C-<delete>' run command backward-kill-word directly?
