Totally different issue.  Computer events are _not_ mandated to follow FIDE
rules in all cases.  But in FIDE events, where computers don't even participate,
it is likely never going to change again...

Absolutely nothing wrong with extending the 50-move rule in non-FIDE events
although it is _Very_ difficult since the programs have to be modified.
