I see your statement is correct, but I'm not sure the overall behavior
is sensible.  Either we consider the information_schema tables to be
catalog tables, and then IsCatalogClass() should be changed, or we
consider then non-catalog tables, and then we should let them be in
publications.  I don't think having a third category of
sometimes-catalog tables is desirable.

Currently, they clearly behave like non-catalog tables, since you can
just drop and recreate them freely, so I would choose the second option.
 It might be worth changing that, but it doesn't have to be the job of
this patch set.
