Right; if this is the same as the ipc functionality I put in nearly 30 years
ago, remember that this simply communicated information about completed
pages to a dvi previewer when machines were hundreds of times slower.

Almost certainly these days it is no longer interesting.  Frankly I would
simply remove any documentation of these features completely.  They
were a bandaid for when processing a file could take many minutes and
people wanted to preview parts of the dvi file as TeX was still running on
the remainder.
