But, consider this example:

  ul.toc a::after {
    font-size: 10pt;
    content: leader('. . . ') target-counter(attr(href), page);
  }

By setting the font size to get leaders right, you also set the size
on page numbers. Typically, you want the font size of the page numbers
to match that of the text.

Again, it would influcence other content in the pseudo-element; you
don't want extra spacing between page numbers.
