Thanks to all for answering!

Actually, the solution with styles is what I came to myself, just used 
aliases instead of creating new widgets (zle -A forward-word 
space-forward-word).
But binding with dot-prefixed widget names seem the most compact 
solution for me: "bindkey '^w' .backward-kill-word", thanks!

Still, both solutions do not seem very obvious, at least for new user.
So maybe we should emphasize it in the documentation?
I think a few extra examples in section introducing 'select-word-style' 
command would be enough.
