Believe you me there are plenty of people looking in to space for possible habitable planets. NASA keeps a database of them.
Whenever future generations make the big leap to the literal new world, there will be some outfit, a developer in charge of stuff and they will have to work through some bugs you see. So at some point, the powers that be will declare a beta phase and encourage early adopters..."We're sure it's safe but just to be clear, you're at your own risk". A Beta Planet.
I was thinking about all of this and then it occurred to me; what if Earth is the Beta Planet?
