\pagediscards is an etex primitive (built-in) command. David is
probably right (since he has been looking at that stuff) but I
don't see the benefit, since we want to get the same page break

I think that would work.
The point is that if TeX breaks the page *not* at a penalty (effective
penalty=0) it flags that by setting \outputpenalty=10000 (which could
never happen naturally).
I see no reason to reproduce the exact output penalty, since you
are looking to get the same page break, so I would probably put a
negative penalty there.
You do not want to hold inserts when performing "supereject"
(-20000), so you do need to release the inserts then.
There are references to \footins in \@specialoutput that have
to be rewritten for the case when \holdinginserts is holding
the inserts. (The whole point of holding them is that they
do *not* come out when cycling through \@specialoutput.)
I'm not sure that it is even possible to maintain the
\@pageht methods when using \holdinginserts.
