In 1999 i remember the big impact of EGTBs at tournament level of DIEP. In 2001 and 2002 i see hardly any game where EGTBs matter. Let alone the 50 move rule within EGTBs. Chance that this matters is only a 1/1000000 of a chance from the times you need EGTB position. Chance it matters for result is even smaller. Eugene is nowadays 'claiming' copyright onto 'his' egtb probing code. Pretty amazing. We can argue about that. We can argue about a lot of things, but EGTBs are no compare with openingbooks. Especially the big progress in endgame of most programs make them really insignificant. I could play without EGTBs coming tournament, simply because chance evaluatoin goes to a lost EGTB endgame in a drawn position now is like a zillion times smaller than a few years ago.
