There is also the hidden style which prevents certain matches from
appearing in the list. So for example, you might do the following to not
list usernames after ssh (but still complete them).
  zstyle ':completion:*:ssh:*:users' hidden true

The style corresponds to compadd's -n option.

The nearest I can quickly get to limiting matches would be something
like:
  zstyle -e ':completion:*' hidden '(( compstate[nmatches] > 10 )) && reply=( true )'
That will not result in a maximum of 10 matches being listed, however
because the style is checked for groups of matches not individual ones.
It also doesn't discern between matches by their length.

It's probably better to combine the hidden style with tag-order and
ignored-patterns.
