Without such a clause in the original documentation, it would be difficult to get the owners to agree on anything and the property manager, who has a vested interest in continuing to run the project and get paid for doing so, has no incentive to push for a sale and dissolution.
This would provide an exit strategy for everyone. Disney does this by selling a RTU, but then Disney gets the reversion right. The reversion right would be cheap at the outset (the original buyers would pay only its discounted value as of their purchase) and it keeps the owners, not the developer, in charge.
