True, not all do, and not all do all the time. But the presence of strategic and tactical choices, for some or all of a game, is preferable than the absence of strategic and tactical choices.I have found that not all players require their choices to be mechanically incentivized, and that no more reason not to pause for eight hours (seconds, to the players, of course since saying "We take a long rest" doesn't take any meaningful amount of time) is needed than that the player's are having their characters behave like real people with goals they consider important and intend to accomplish - which means not spending more time resting than is actually needed, because resting isn't "gettin' it done".
We can disagree about whether long rests are the place for choices to be introduced, but I do not feel that I need to play according to a tweet that works against what I see as the clear intended meaning of the text. And, as I said above, I have no problems with tables that choose otherwise.
We all create the game we want. The rules facilitate that. They are not meant as a crutch or an obstacle, but as a means of stimulating the imagination of real players having fun in a game. That, in my opinion, should be the goal.
