I don't know. Nut let's see.

Ok, at least with both sides having tables... or at least input about the
importance of certain endgames. See below.

This might be true but what does it mean? I'm referring to the fact that the
leading programs use a feature for the early detection of certain endgame
possibilities. So progs do not only rely on the tables themselves but also on
early help for judging much later and only "possible" endgames. At least I
understood it this way. Now my point is, that if the tables are not allowed, the
mentioned control is impossible what increases the possibilities to make basic
mistakes in the middle game. Seems trivial enough.

We don't know much about the advantages because nothing is been made public.
