Putting a character in WORDCHARS tells Zsh to treat it as if it ispart of a normal "word". (i.e. that it *isn't* something that marks a word boundary.) 


I very much doubt that. In my zsh, the untouched value is::

*?_-.[]~=/&;!#$%^(){}<>
I.e. pretty much the characters I expect to be word boundaries when I hit ^W.
"Some relevant sections from the manual" or "Far more than you ever wanted to know about WORDCHARS"

The word styles available are as follows. Only the first character 
    is examined.

            bash   Word characters are alphanumeric characters only.

            normal As in normal shell operation:  word characters are
alphanumeric characters plus any characters present 
                   in the string given by the parameter $WORDCHARS.
shell Words are complete shell command arguments, possibly 
                   including complete quoted strings, or any tokens
                   special to the shell.

            whitespace
                   Words are any set of characters delimited by
                   whitespace.

            default
                   Restore the default settings; this is usually the
                   same as ‘normal’.



So, I suspect you're using something other than 'normal' word style.

e.g., in my Zsh:

## Let WORDCHARS contain '.' and '/' (your 'untouched value'):
$ echo WORDCHARS
*?_-.[]~=/&;!#$%^(){}<>
$ /this/is/a/very/long/path (Ctrl+W)
                         ^ <-- cursor
$
^
$ this is a.domain.name.example.com (Ctrl+W)
                                 ^
$
^

## So, take '.' and '/' out:
$ vared WORDCHARS
*?_-[]~=&;!#$%^(){}<>
$ /this/is/a/very/long/path (Ctrl+W)
                         ^
$ /this/is/a/very/long/
                     ^
$ this is a.domain.name.example.com (Ctrl+W)
                                 ^
$ this is a.domain.name.example.
                              ^

Personally, I take '/' and '=' out (not '.').

Best,
Ben
P.S. I composed this before realizing you'd replied off-list. Feel free to forward it to the list. 


Sorry for my incompetence in using my own mail client.
At risk of hijacking this thread, I'm now puzzled. The behavior above simply doesn't occur for me.
I might add that I use vi keys, does that matter? I might also add that if I do dW in normal mode, it deletes ${WORDCHAR}s as well. But not using ^W.

I guess today is simply not my best day with my mail client. The above are three messages that I think were supposed to be on the list.
