Notice you say "players" as if they are monolithic and all want the same thing. One table. One DM. Many players. That removes part of the equation unless they are all in agreement. And if they are, my guess is the DM is already in agreement too.DM creates and runs the world, players play the characters.
Players don't tell the DM how to build or run the world. the DM doesn't tell the players how to player their characters.
Just because the characters start an adventure, doesn't mean they are bound to finish it.
And the DM runs the world, but the world needs to be generated in order to contain some sense of storytelling logic. So, it is a courtesy extended to discuss any radical changes of course. Much like a drummer doesn't just start playing a new song in the middle of another song and then force the others to have to change songs.
