In principle, that could be done.

But doing it correctly would be a bit more involved than just generating
the TOC multiple times, which can be quite time consuming for big
documents.

The correct way would be:

  0. Switch to Page media type.

  1. Update the buffer, that fills the auxilliary documents.

  2. Update the TOC.
  
  3. Get the displayed text of all pagerefs used in TOC.

  2. Update the buffer, that updates pagerefs.

  3. Get the displayed text of all pagerefs used in the new TOC.
  
  4. If there are new or changed pagerefs, go to 2.

  5. Restore the initial media type.

The main reason why it is not currently done is probably that nobody has
implemented it yet.

Because the "abstract" macro does not create a TOC entry. Well, maybe
that is not the answer you were looking for... Probably this is not
generally considered useful and nobody has implemented a way to make
this optional.
