I'm not sure what you call "unit", but IMHO, the notion of unit
should be different from the notion of argument. For instance,
I would agree that a URL could be regarded as a unit, and after

  echo "The URL is: 

it makes sense to paste a URL. So, the context should matter.

Or perhaps there should be a function that does all the work for
URL handling, e.g. currently

  autoload -Uz url-quote-magic
  zle -N self-insert url-quote-magic
  autoload -Uz bracketed-paste-magic
  zle -N bracketed-paste bracketed-paste-magic
  zstyle :bracketed-paste-magic paste-init backward-extend-paste

in case there would be future changes.
