Like the other rules (including player resources like Rope Trick, snd the staggeringly powered-up Tiny Hut) around resting, it does seem at odds with 5e's DM Empowerment and classic-feel imperatives.. Any speculation as to the point of it? Where is the value in denying DMs the obvious tool for interrupting long rests!?
Unless we acknowledge that a player-driven 5MWD is part of that classic feel? The DM is still Empowered to dial up encounters to make them challenging even to a full-rested party. The 6-8 encounter guideline is then, presumably there for DMs who wish to impose it in a more linear style of campaign. For those running a sandbox and/or rewarding old-school skilled play/strategy/CaW, the issues the guidelines are meant to address - class imbalance and, particularly, encounter difficulty - are of no concern, or even desirable.
