<div class="chapter">
  <div class="move-to-end">...</div>

div.move-to-end { float: to(end-of-chapter) }
div.chapter::after { content: from(end-of-chapter) }

I'm not convinced by these use cases. If you want to move something to
the end, I think you should move it to a place in the structure (e.g.,
chapter or section, as per the example above), not to a certain page.
The content you are moving may take up more than one page and the
moved content will therefore not (only) be on the last page anymore.

If there is a good use case for setting different headers/footers on
the last page, I may be convinced. Is there?

It's slightly harder to implement :last than :first, because the
formatter doesn't necessarily know that a page is the last until it
has been formatted. Loops may occur.
