"We came up with a way to make all your tournaments run faster with zero effort on your end"
"Okay!"
I'm being pedantic, but it doesn't run faster, you still have the same number of matches to play total.
The change is that it frees up the scheduling on Friday to allow for special events and exhibitions that will receive far more viewership and interest than random early pool matches will. Genesis 3 has a Melee draft crews battle, a Wii U regional crews battle, and The Melee Games finals all scheduled to happen on the main streams on Friday.
(That said, for The Big House 5, we were able to make the Melee Regional crew battle happen on the Friday without any schedule conflicts and without advancing top players automatically into Day 2.)
Bottom line on this issue is that it's a decision made for the benefit of stream viewers to the detriment of ordinary tournament entrants.
