People that use beds would have hidden in their house during night anyways, so it really didn't make much difference, except allow the player to move their spawn point, encouraging more exploration.
While that sounds true, in practice the waiting can cause even a cautious person to do risky things. For example running out to harvest a tree because you want to make something but don't have enough wood on hand. Or run over to the chicken pen to collect the eggs. Or attack that skeleton outside the door because you could use the arrows it might drop.
I learned very quickly in alpha to make a fairly self contained base to keep me busy at night and also to go mining/caving at night to pass the time productively. To this day I don't use beds except in superflat or custom maps where you might get lost without setting a reliable spawn point.
