Mostly a QOL change to waste less time.
When a lot of people die and the game's result is already known, the game should just skip the "blah blah has died, we found a will" and go directly to "Faction has won!"
E.g. Arso ignites 4 people and wins, but he still is forced to watch every single dead person be revealed even though we all know he won. Since he already won, it should go to game over screen FIRST, then show roles if for some reason you're interested in that (or just end the game altogether).
This also relates to how "We could not determined Player's role" takes an oddly long amount of time to be shown, which is a minor annoyance.
Honestly, some of these slow transitions are why people often be like "i was watching youtube sorry". It gets boring after a while.
